Arvella Louise Thomas was 14 when she was murdered on April 11, 1978. She was last seen about 11 p.m. at the Morse Avenue elevated train stop in the Rogers Park neighborhood of Chicago, asking passersby for fare to get home. Her body was found the next morning in Skokie, Illinois.

Investigators determined Arvella had been subjected to severe trauma and that evidence suggested a sexual assault. Decades later, convicted murderer Ralph Andrews was implicated after another inmate, wearing a concealed recording device, captured Andrews allegedly bragging about the killing; Andrews was subsequently indicted in connection with Arvella’s murder.

The case has long haunted Arvella’s family and community. Does anyone have memories of Arvella, the Morse Avenue stop that night, or information that could help fill gaps in the timeline?
