This RIGG marks the end of an era.
On a sunny summer day in 2022, I met Professor David Gurney for the first time at the Runcible Spoon Bakery & Cafe in Nyack, New York. We had been introduced online by a mutual friend and business colleague, Margaret Press, who had been my supervisor at DNA Doe Project and had worked closely with David to form the Investigative Genetic Genealogy Accreditation Board (IGGAB). Margaret noted that we lived close to one another and might enjoy working together on investigative genetic genealogy projects.
Little did we know, at the time, that our conversations over iced coffee and pastries would develop into dozens of solved cases and answers for waiting families. Our scribblings about potential programs would foreshadow memorable summer conferences and hundreds of alumni from novel educational experiences we developed together. Discussions of our passions – his, miscarriages of justice and mine, Latin American unidentified remains cases – would unfold into long-term research projects and collaborations with positive effects that have rippled through the field of IGG.

David and I shortly after we started the 69ɫƵ IGG Center in 2022. At this time, there was no IGG lab, no IGG certificate program, and no RIGG Conference!
Over the years of our work together, I have noted David’s apparent inability to “coast”. As a team, we have never sat back to enjoy the fruits of our labor, accepting the status quo. As our programs have grown, we have hired more people, taken on more cases, and raised more funds to ensure that the power of investigative genetic genealogy can reach as many cases as possible.
To that end, David has never said “no” to a good idea, even when it is difficult to implement. Our Latin American DNA Project, our participation in conferences around the world, our pioneering education programs, and a lot of other very hard work – have happened thanks to David’s leadership and advocacy for our IGG team.

Our first DNA Drive in Tucson, 2023.
Investigative genetic genealogy leadership can be a thankless job. During his tenure as the Director of the 69ɫƵ IGG Center, David has been at the helm as we received backlash from critics worldwide. We have repeatedly been on the receiving end of articles and social media posts disparaging our work and questioning our intentions while we strove to provide justice for victims of violent crime and overturn wrongful convictions. Aside from that, our working relationships in The Center are not always peaceful and harmonious – we have experienced disagreements that threatened our partnership and divested us of our morale. However, David’s ability to push through even the most challenging situations and smooth over disputes is admirable, if not positively transcendent.

With colleagues in West Palm Beach days after a ToS change rocked our world in 2025.
Outside of his work in IGG, David’s passion for Law, Justice, and Morality – which is also the name of the class he has taught every semester at Ramapo – is apparent. Walking by his office, students are guaranteed to find printed copies of the United States Constitution and Bill of Rights perched on the dado rails on either side of his door. As a professor, David has strived to ensure that the young adults in our society are educated about their rights and freedoms as well as ethical and moral dilemmas we are bound to encounter as humans. The shelves of his office include not only works by Thomas Paine and Franz Kafka, but also religious texts and American literature he may use to illustrate ethics and morality in our modern world. For his innovative methods and his dedication to teaching, David was awarded the Henry Bischoff Excellence in Teaching Award in 2023.

As a leader, an advocate, and as a friend – David Gurney will be sorely missed when he steps away from his role from the IGG Center this summer to relocate to the southwest. I have no doubt that his impact on the field of investigative genetic genealogy will continue. As I said, the man cannot “coast” and we can’t wait to see what he does next.
Thank you, David, from all of us.

Tantae molis erat Romanam condere gentem. (OK, OK, but see the note below on hubris.)
Leading the IGG Center at 69ɫƵ for the past four years has been the greatest honor of my professional life. The people and experiences (the good, the bad, and the ugly) have inspired and re-shaped me in ways I could never have predicted. I am proud of every team member and the work that we have done together. Thanks to the dedication of the team, the IGG Center rests on a solid foundation. As my wife and I make the move back to Arizona with our family, I leave my role with gratitude and confidence. The field of IGG has as its goal to provide justice and answers to victims and families, and the IGG Center is now a leading light in that effort. The center’s missions of providing proven casework, expert education, and imaginative research are well-established. With these accomplishments in mind, innovation and expansion benefit from the temporary turmoil of restructuring, and so I believe that the impact of the IGG Center will only increase in the years to come.
Beginnings
When I came to 69ɫƵ as a professor in the fall of 2019, I had an idea—more a dim flickering, really—to start a clinical program that combined my earlier work on wrongful convictions with the new investigative method that had identified the Golden State Killer and already led to one exoneration, Christopher Tapp. The problem was time. As a new professor teaching a full load of classes, time was in short supply. Then, in the spring of 2020, as COVID-19 brought turmoil and uncertainty to the world, one of the many odd and unexpected outcomes of that awful event presented itself: time. For someone who did not yet have kids to take care of and was fortunate enough to have family that avoided the worst of the disease, the most sudden impact of COVID was a surplus of that previously scarce resource. It was in those long, strange months that I had the time to blow oxygen onto the idea of creating an investigative genetic genealogy program at Ramapo.
The need was clear. A relatively small number of practitioners were solving cases with IGG at that time. And there were potentially hundreds of thousands of cases—including unsolved violent crimes, unidentified remains, and wrongful convictions—that could benefit from the method. To work those cases, an army of well-trained practitioners would be needed. After an intensive course in genealogy in the summer of 2020, mentoring from IGG pioneers such as Lori Napolitano and Margret Press, and innumerable fits and starts, I began to put the pieces together for a program at Ramapo. What I didn’t know then was that my most significant IGG education was ahead of me.
To convince Ramapo—and myself—that the idea was viable, I created a stand-alone class for undergraduate students where they would learn how to do IGG using simulated cases with DNA helpfully provided by several of my friends (thanks Paul, Sam, and Katy). The students were enthralled and rose to the challenge mightily (one of them, Emma Brennan, later graduated from the IGG Certificate Program).
There was still the problem of convincing Ramapo. An avenue opened when Ramapo took on a new president in the summer of 2021. With the encouragement of my ever-supportive dean, Aaron Lorenz, I submitted a proposal under the president’s call for innovative ideas for new centers at the college. In the early summer of 2022, I formally presented the idea, where I emphasized the public good of IGG and the potential for Ramapo to become a hub for IGG education, practice, and research. To my delight, the proposal was approved. Now . . . to build an IGG Center.
(A note on hubris: in the initial thoughts about the center, I imagined doing the work largely on my own. Thankfully, Nemesis arrived sooner rather than later, and slapped sense into me.)
What happened next is one of the innumerable moments of serendipity that have accompanied the birth and growth of the IGG Center. Margaret Press of the DNA Doe Project suggested that I meet up with an early DDP volunteer who by then was the director of education and development at that organization. Her name was Cairenn Binder, and she happened to live right across the Hudson River from my home in Nyack, NY. We met at a coffee shop (Runcible Spoon, for the curious) to talk shop, with no agenda but sharing notes: Cairenn picking my legal brain and me picking her IGG brain. I can’t recall if it was at our first or second meeting that I rashly, and half-jokingly, suggested that she give up her nursing job and come work at Ramapo. I had no authority to offer anyone a job at that point, and I knew that adding another paid, full-time position to an already-speculative idea would be a hard sell to Ramapo. But suggest it I did, with all of the concomitant disclaimers about unlikelihood and uncertainty. The idea landed and took root, and within a month I’d emailed Cairenn an outline of how the center would operate and a proposed job description.

Foundations
Looking back now after four years, I am amazed at how nearly every speculative goal laid out in that email has been realized—and exceeded. Cairenn and I were, from the start, eerily united in our visions for the center and have remained so through the ups and downs of the past four years. With Cairenn at the helm of the certificate program, what began as the upstart education program in the field quickly became the go-to destination for practical, hands-on IGG training. Skeptical initial receptions to our outreach to law enforcement, medical examiners, and wrongful conviction organizations has, through a record of reliable communication and successful leads, turned into a steady stream of referrals from our, now, trusted partners and new contacts alike.
Building the center has not been without challenge. We have faced many moments of struggle and stress, along with long days and nights. Each member of our team has made sacrifices of time and energy that I am astounded by and endlessly grateful for.
Today, the IGG Center is a recognized leader in the field. Our team has provided leads in nearly fifty cases, one of which led to the exoneration of two brothers, Robert and David Bintz. Over 350 individuals have graduated from the IGG Certificate Program and are collectively responsible for helping to solve sixteen cases during their training. Four cohorts of our IGG Bootcamp (from where I write this post as a new lead is quickly developing around me) have spent an intensive week solving cases in person at Ramapo. Our annual RIGG conference, now in its fourth year, hosts IGG luminaries and neophytes alike with expert presentations, topped off with what we lovingly call Ramapo’s “escalated” BBQ. Research at the center has produced thirteen scholarly articles and book chapters and helped influence legislation. Our Latin American DNA Project has filled the databases with hundreds of new testers. We have helped train international colleagues in the United Kingdom through our partnership with Sheffield Hallam University, and recently Cairenn and Tracie held the first overseas bootcamp in Australia. The number of conferences where we have presented is nearly uncountable, from ISHI to the Innocence Network to IHIA and more. Media has covered the work of the center with a plethora of news articles, interviews, and features throughout the United States, and the world.

All of this has been a team effort. What began with myself and the quick addition of Cairenn has grown to a team that is the apogee of the IGG world. Tracie Boyle, our case manager expertly shepherds cases from intake to lead generation, providing regular updates to agencies along the way. Julian Rebelo, our staff IGG practitioner, works doggedly on cases and oversees our teams of volunteers that put the long, strenuous hours into casework. Our four certificate program assistants, Marianne Hess, Christine Fiechter, Tiffany Sowell, and Diane Bates provide practical and patient mentoring to our cohorts of students. Traci Onders and Monique Platt, our first assistants, were instrumental in building a successful program.
Promotion of Cairenn and Restructuring
And Cairenn Binder. From the earliest days of the center’s formation all the way to the present day, Cairenn has been the beating heart of the IGG Center. Her drive and resilience are unmatched in anyone I have encountered in my professional career. As a mentor to students, she is professional, approachable, and patient. As an IGG practitioner, she is nonpareil in her quick wits and ability to spot trends in the tree—indeed, she is, without doubt, the most impressive practitioner I have witnessed at work. Watching her work cases in the first months of meeting her was an education in IGG beyond what I had considered possible up to that time (her facility with Millennial and Gen-Z slang alike has been another education in its own right!) As a presenter and communicator, she is clear, conscious of her audience, and never put off by tough questions. As a colleague, she is a fount of inspiration, and I am privileged to call her a friend.

It is because of Cairenn that I feel enormous confidence and optimism in leaving the IGG Center. Over four years, I have witnessed Cairenn develop as a leader at the center and in the field as a whole. And so it is with boundless confidence that I announce the promotion of Cairenn Binder, MS, AIGG, to the role of director of the IGG Center at 69ɫƵ. Cairenn’s relentless passion for the power of IGG to do real good in the world is a testament to her character and a cynosure for the entire field.
Along with Cairenn’s promotion comes additional restructuring. Tracie Boyle will rise to director of case management. Tracie’s dedication to cases is manifest every day, and her shining optimism has been a beacon for me in hard times. To lead the certificate program, a newly hired director—to be announced—will come on board soon. And Marianne Hess and Christine Fiechter will step up as senior program assistants.
As I leave the center, many of the projects we’ve been working towards for years are finally coming to fruition. I know that each one of those projects will be carried forward with aplomb under Cairenn’s leadership.
Thank You

There are many more people to thank, more than I can possibly list here. Nick and Susan Vallario, whose generous donation launched the IGG Center in 2022. Nick passed away earlier this year, and I miss him greatly, but I know he would be proud of where the center is today and where it is headed. Stan Richmond, who has supported the center in a variety of ways since its founding. Aaron Lorenz, my dean, who has since moved on to a well-deserved vice provost position at Salve Regina University. I could not have navigated the early years of the IGG Center without his unwavering support and steadying advice. Susan Gaulden, Ramapo’s previous provost, who saw the early potential in bringing IGG to Ramapo. Kathy Stasis and Chris Tredici, from the budget office, who have graciously fielded my many inquiries about the byzantine budget systems of the college. Chris Romano, a Ramapo VP who has never missed an opportunity to trumpet the mission and success of the IGG Center to audiences of alumni and Ramapo boosters. President Jebb, who took a risk in approving a new and untested idea from a fresh and then-untenured junior professor. Provost Middleton, who helped remove barriers to the center’s growth.
All of the Ramapo staff from housing, dining, IT, and communications who have provided the unseen and too-often unsung foundations that make the IGG Center function.
My colleagues in the law and society program at Ramapo—Jeff Ellsworth, Mia Serban, Sangha Padhy, and Atieh Babakhani—who stood behind my unconventional path (not something, I imagine, they anticipated when they hired me as a professor in 2019). Naseem Choudhury, from the faculty union, who was always willing to listen and offer advice.
Thank you to Margaret Press, CeCe Moore, and Lori Napolitano for supporting and mentoring me when I was a complete unknown. Thanks to Greg Hampikian for providing sage advice on building a practical program within an academic setting. To Kelly Harkins Kincaid, thank you for providing a steady stream of patient responses to my lab questions.
To our agency partners, and the families and victims you represent: you are the reason that we do what we do. It has truly been an honor to assist you in providing answers to the families of the missing and justice to victims of violent crime. Thank you for trusting us with your cases, and thank you for the work that you do.
To Jim Mayer from the Great North Innocence Project: thank you for helping me to fulfill one of the initial goals of the IGG Center in helping to free two wrongfully convicted men from prison, and for giving me a full circle moment working on a case from the organization that first put me on the path that has led me here.
Our students and volunteers who have dedicated thousands of collective hours in the service of justice: thank you, thank you, thank you. Never forget the significance of the work you do.
Tracie, Julian, Monique, Tiffany, Marianne, Diane, Traci, and Christine: thank you for who you are. I am fortunate to know you and to have had the opportunity to lead such a team of remarkable people. Thank you especially to Cairenn, who came like a shooting star over a battlefield when I met her in 2022, and to whom I am forever grateful.
And, most of all, thank you to my wife, Arthi, for standing by me through the long nights and weekends when I was busy with the center, and the frequent travel that took me away from home.
To every IGG practitioner, law enforcement officer, medical examiner, forensic scientist, and attorney, named here and otherwise, who has recognized the power of IGG as a tool for justice and works on behalf of the nameless, those who have been swept by violence, and the wrongfully convicted, draw strength from the good work that you do. There is much more noble work to be done, thousands of cases representing victims and families in search of justice and answers, and you are needed. Take heart. I leave you with these words:
that which we are, we are;
One equal temper of heroic hearts,
Made weak by time and fate, but strong in will
To strive, to seek, to find, and not to yield.

Circling back to our end-of-year blog post from 2024, I see we had a resolution post more in 2025. It looks like we fell extremely short of that goal! With that said, it was an extremely busy and productive year for us at the IGG center and we had plenty to do! Here are a few bright spots in what was most certainly an incredible year.
Marianne Hess, IGG Program Assistant:
“My favorite moment of the year was when our team was able to provide a lead for a recently found, unknown Jane Doe. This case took over 18 months, and the team spent 3000+ hours working on the case. It is especially close to my heart because it was the very first case that I worked on as a volunteer after I completed the Ramapo IGG Certificate Program.”
(Note: The case Marianne is speaking of is one yet to be announced.)
David Gurney, IGG Center Director:

“Watching the continued success of Ramapo’s Latin American Project was one of my favorite moments from 2025. Latin American Does are people who deserve to have their names back, and their families deserve to know what happened to their loved ones. In the project’s third year, six of our hardworking volunteers put their sweat (literally!) into handing out 100 FamilyTreeDNA Tests at the Tucson Festival of Books, helping to ensure that Latin American Does are given a better chance of having their names finally returned to them.”

“The keynote speech at our conference, RIGG, this year was given by two of my favorite people in the world — Lauren Felix and Bob Taft. Lauren was one of the first students in the IGG Certificate Program, and Bob was present at the launch of the IGG Center in 2022 — I’ve worked with him on cases since 2018! Seeing these two talk about their journey in IGG and the impact of their work on families who needed them felt like a full-circle moment. That happy memory will be one that keeps me content through all of the tumultuous times in the field of investigative genetic genealogy.”

This year, we will have the highest number of bootcampers ever on Ramapo’s campus for a full week of casework and collaboration. Bootcamp is one of the most fun weeks of the year for us as staff, but it’s not just fun – it’s a lot of work, and can be overstimulating and exhausting, too!
In this blog post, I will share my top 5 tips for having a great time at IGG bootcamp on Ramapo’s beautiful campus in Mahwah, NJ:

Although we’ve been neglecting the blog lately (our New Year’s Resolution is to post more), we have had a busy and fruitful year at the 69ɫƵ IGG Center. Our staff spent this week reflecting on our favorite moments, which we’ve compiled here to share.
Marianne Hess, IGG Program Assistant:
“My favorite moment for the the IGG Center this year was when the Bintz brothers were exonerated. On a personal note, when I first learned about IGG I thought that it could be a great use of IGG. I was so excited the first time I heard someone mention IGG in that context – it was David Gurney at ISHI in 2022!”

David Gurney, IGG Center Director:
“Seeing the Bintz brothers exonerated a result of the work of IGG Center staff and students was an incredible moment in 2024. Representing only the third and fourth individuals exonerated through IGG, their cases demonstrate the power of IGG as a tool of justice writ large. The exonerations also exemplify the value of Ramapo IGG Center’s collaborative approach to casework. I am so proud of our students and staff for helping to give Robert and David Bintz their freedom and finally achieve justice for Sandra Lison after 37 years.”

Monique Platt, IGG Program Assistant:
“My favorite moment of 2024 was the first day of Boot Camp. There’s a unique energy that you feel right before any case launch, but it’s wholly different when there are so many of you in the same room ready to dig in on the same case. Anything can happen. You don’t know yet whose lives could be impacted by the work you’re about to do, but there’s something very special about knowing you’re all working towards a shared outcome.”

Boot campers at the 2024 IGG Summer Bootcamp
Traci Onders, IGG Program Assistant:
“One of my favorite moments was meeting Allen Grasser, the brother of Norm Grasser, and learning about what it was like for him to have a brother missing for over four decades, and what it meant to finally have some answers as to what happened to his brother. Rhinelander John Doe was identified as Norm Grasser by Ramapo IGG’s first cohort and it was a special honor for our cohort to be able to hang out with Allen during RIGG and a special privilege for me to call him my friend.”

Tracie Boyle, IGG Center Case Manager and Administrative Assistant:
“There were so many great moments this year, but if I had to choose one that stands out, it’s definitely CrimeCon. We worked hard, but we had a lot of fun too! We met some wonderful (and inspiring) people, created new partnerships, reconnected with familiar faces we hadn’t seen in a while, and enjoyed some really great conversations.”

Cairenn Binder, IGG Center Assistant Director:
“I am cheating, because I update the website so I get to pick more than one favorite moment. Apologies to my coworkers! My favorite moments were those where we got to meet with our alumni and our colleagues in the field for in person meetups and collaborations. I4GG in San Diego stands out as a highlight, as do the alumni party and keynote nights at RIGG. Aside from that, quiet moments on campus and enjoying the beautiful scenery are little pleasures we can’t take for granted.”

Robert Bintz and David Bintz
This blog is an update to David Gurney’s previous blog post: New lead in 1987 Wisconsin murder of Sandra Lison could produce third IGG exoneration
In June of 2023, the 69ɫƵ Investigative Genetic Genealogy Center was tasked with identifying the contributor of a DNA profile developed from blood and semen found on the dress of Sandra Lison. Ms. Lison had been kidnapped, sexually assaulted and murdered while working at the Good Times Bar in Green Bay, Wisconsin in 1987.

Sandra Lison
When our IGG bootcamp students produced a new lead in the case in July of 2023 and identified William Hendricks as the possible suspect, we knew there might still be a long road ahead. The State of Wisconsin would need to agree the lead was significant, exhume William Hendricks’ remains, compare Hendricks’ DNA directly to the crime-scene DNA, and, if he was a DNA match – agree to vacate the convictions of Robert and David Bintz.
Thankfully, the state was cooperative, and the remains of William Hendricks were exhumed in May of 2024. Due to the age and condition of the remains, there was some difficulty in developing a suitable DNA profile. To expedite the process, one of our generous donors covered the cost of testing at a private lab, who developed a full profile. An analysis by the Wisconsin State Lab demonstrated overwhelming statistical evidence that the previously unidentified crime-scene DNA came from Hendricks.

The exhumation scene
Recognizing the significance of the DNA result, the State of Wisconsin conducted a renewed investigation of the case.
DNA report comparing Hendricks’ DNA to crime scene DNA
On September 24th, we were scheduled to present this case at the International Symposium on Human Identification with Jim Mayer of the Great North Innocence Project. Although we had hoped for a conclusion prior to our presentation, the case remained in limbo with a hearing scheduled in October and the Bintz brothers still in prison for a crime they did not commit.
Unbeknownst to us, just hours before our presentation, Jim had received a phone call that changed the course of the case entirely. On stage, he shocked everyone in the room (including his co-presenters) by sharing that the state’s investigation revealed additional evidence of Hendricks’ guilt. All parties now agree that two innocent men have been sitting in prison for twenty-five years. An expedited hearing was called, and the next day, the State of Wisconsin formally acknowledged the Bintz brothers’ innocence, and a judge granted relief. They will be released shortly.

David Gurney, Jim Mayer and Cairenn Binder at ISHI 2024 shortly after it was revealed that the Bintz Brothers’ exoneration was imminently forthcoming.
When Jim Mayer of the Great North Innocence Project initially broke the news of Hendricks’ identification through IGG to his client, Robert Bintz’s first reaction was relief that his daughter would finally know that he did not commit this horrible crime. After twenty-five years, and with the help of IGG, the truth has finally been revealed, and a measure of justice has been given to all of the victims in this case.
