It’s that time of year when people think about interesting presents to give and you might have hit on a unique idea: DNA testing. Perhaps you want family and friends to find out about health risks. Perhaps you saw an advertisement and thought this saves you from going into crowded malls or because someone you know is a history buff and this is what they want. Whatever the reason, by getting DNA tests on yourself or others, you’ve joined millions of people around the world who send off a swab of their cheek or a saliva sample and get information using their DNA.
With your DNA test you’ve done something that you probably never thought you’d do: help catch criminals by solving cold cases.
In December 1983, Sean McCowan and his brother stayed overnight at the apartment of his sister, 22-year-old Erin Gilmour, "She … would do that frequently, we would sort of go over there and spend the night and just hang out with her and then we'd all climb into bed together and watch movies and eat popcorn," said Sean McCowan, who was 13 years old when his sister was killed. "It was five days before Christmas, and so … we all woke up the next morning. Erin drove my brother Kaelin back … to my mom's house. And I ... went out actually to do some Christmas shopping. And we said our goodbyes and that was the last time I saw her.”
That evening, Erin was brutally raped and murdered in the same apartment where she and her brothers watched movies and ate popcorn the night before.
Four months earlier, in August of 1983, Susan Tice, 45, was also brutally raped and murdered in her Toronto home.
”My mom was supposed to have dinner with my aunt and uncle and when she didn't show up, he went to the house to find out where she was," said her daughter, Christian Tice, who was 16 at the time. "We had like the best family… we were very, very close… we did everything together. We were one of those houses where everybody else's friends were always over… And everyone called my mom Mrs. T or Ma.”
In 2000, DNA technology showed that one person was responsible for both crimes but police were still unable to identify the man.
In November 2022, almost four decades later, Joseph George Sutherland was arrested and charged with these two brutal crimes.
How were they able to identify and arrest Sutherland?
“In 2019, police began using a technique called "investigative genetic genealogy” to identify the suspect's family group. The process involves cross-referencing DNA found at crime scenes with DNA samples voluntarily submitted to services like 23andMe or Ancestry.ca and then uploaded to open-source databases.”
Essentially, this arrest was made possible by the millions of people who got DNA tests for many reasons but none of them to finally jail a brutal rapist and murderer.
So, when you buy a DNA test for yourself or someone you care about, you’re not only finding out interesting things about health and family history. You are helping find criminals who would otherwise have walked free.
Det.-Sgt. Steve Smith, lead investigator on the cold case, “called the investigation the "most complex" case he's worked in his 25 years on the force and credited the recent development to genetic genealogy. He said that Sutherland had never previously been a person of interest in the killings. "If we hadn't utilized this technology, we never would have came to his name.”
There have been many valid privacy concerns about the DNA databases of companies that provide these tests. However, the use of these data bases to catch criminals, in my opinion, is not merely fair but also just. Sutherland has walked freely among us for over four decades while those who loved his two victims have had justice denied to them. Using databases to finally arrest and try Sutherland is fair and just to his victims and their families.
The most powerful argument to support using these databases in this way, are the pictures of Sutherland’s victims. These photos are over 40 years old. Both Erin Gilmour and Susan Tice should have had many more photos taken of them since 1983, when they became frozen in time because they were brutally murdered.
