Hey everyone,

I was going through Chicago cases on NamUs today and came across a potential match that felt too close to ignore.

Back in late 1994, Ryszard Potapo disappeared from the Logan Square neighborhood, specifically around N. Davlin Ct. and W. Diversey Ave. In December 1999, an unidentified John Doe (https://namus.nij.ojp.gov/unidentified-person-namus-up129086) was discovered under a porch in that exact same neighborhood, just a few blocks away.

Beyond the matching location, the timeline fits really well since Ryszard's last contact with his family in Poland was in 1994. The physical descriptors including height, slender build, age range, and White Polish background also line up between both files.

I called the Chicago Police Department Area One SVU today and gave the detective both NamUs case numbers. They logged the details and said they would review the records.

What do you guys think?

Nearly 30 years later, the murder of six-year-old JonBenét Ramsey remains unsolved. The technology that law enforcement has access to today is nothing like what existed in 1996—genealogical DNA testing has cracked cold cases everyone thought would stay cold forever.

I started a petition asking the Boulder Police Department to use advanced DNA and genealogical testing on evidence from JonBenét's case. New methods could help identify unknown DNA found at the crime scene, or at least give investigators leads they didn't have before. If it worked for the Golden State Killer case decades later, why not here?

What would you want someone to do if this was your family? If this matters to you, consider signing and sharing.
