WAUKESHA, Wis. — Katie Dougherty has worked at the Waukesha County Medical Examiner's office for more than 10 years. As part of her job, she gets to solve mysteries.

In 2011, she says she was handed the cold case files for the county. Included in those files was a case from 1977. A man died while driving a stolen car near Delafield, and he left detectives little to work with.

"The only identifying items he had with him were a lighter that said 'to John love Lauri' and an envelope with medication tablets in them that had the name Scott on them," Dougherty said.


"I always told the detectives that I was going to get this solved," Dougherty said. "I didn't know when. I didn't know how and I knew I was going to need help, but I said we're going to solve this case and it's going to be forensic science that does it."

In 2015, the Delafield John Doe was exhumed to collect a DNA sample. It was sent to the University of North Texas, where it was compared to samples in CODIS, the FBI's Combined DNA Index System. It's a database designed to help investigators see if the DNA they have was collected elsewhere, either as evidence collected from a crime scene or known offender or arrestee profiles.

But in Delafield Doe's case, there were no matches. His case remained a mystery.

Dougherty then reached out to DNA Doe Project, a group of volunteer investigative genetic genealogists.

Kevin Lord, the Director of Lab and Agency Logistics for DNA Doe Project said the DNA in the Delafield Doe case had a problem.

"The DNA, in this case, the quality of the DNA was really not very good at all, that was one of the big challenges in this case," Lord said.

Over time other microorganisms made their way into the body, making it difficult to obtain a sufficient sample.

He sent the sample to the HudsonAlpha Institute for Biotechnology, located in Huntsville, Alabama, where the DNA sample could be further analyzed.

"The ideal situation is that they enter it and there is a close family match, and we're able to solve it right away. But in this case that didn't happen," Dougherty said. "All of his matches were very distant. At that point they put me in touch with Jenny."

Jenny Lecus, an investigative genetic genealogist with DNA Doe Project, wasn't far away, located about 20 miles away in Franklin, Wisconsin.

In May of 2020, she and her team of volunteers were able to start processing the DNA using data uploaded by genealogy websites users who opt to share their information.

"What we do is we try to identify MRCAs, Most Recent Common Ancestors, between the matches, and we hope for different groups of these so we can see how their families might be linked together," Lecus said.

"We were able to identify several common ancestor couples of interest and some of them went back to the 1700s, but we were able to narrow it down a little further and so we gave those names to Katie, the medical examiner, and then she was also looking at them and she was able to identify one of their descendants," Lecus also said.

Dougherty said she offered a hand in the research, and eventually found a marriage certificate for John Lindbergh Scott.

"He had the lighter that said 'To John, Love Lauri,' so we had the John name. And then he had an envelope with the name Scott on it, so there we had the name Scott," she said.


Last November, Waukesha County officials were finally able to announce they had identified John Scott, 44 years after his death.

"We were able to get in contact with John Scott's sister, Mary Jean Nunn, who went by Jean, and she was more than happy to provide us with a DNA sample," Dougherty said.

"I just found out a few days ago that Jean Nunn passed away unexpectedly, and I am so grateful that all of us were able to give that, this answer, before she passed. Because I know she was incredibly grateful for it," she also said.

DNA Doe Project is actively working on additional unidentified cases in Wisconsin and across the country.
