Carlos Felix was 27 when he was fatally shot in Saint Louis, Missouri, on April 26, 2018. Known to friends and family by the nickname 3 Los, he was killed in the North City area — a shooting that family and acquaintances remembered as another loss to the community’s struggle with gun violence.

An online memorial drew more than one hundred candles and many tributes from people who knew him. Messages from cousins and from someone identified as Mrs. Felix included affectionate farewells, and the memorial profile included references to children, suggesting he may have been a father.

Does anyone who knew Carlos or was in North City that day have information that could help clarify what happened?
