Deborah McCall was 16 when she left Downers Grove North High School in Illinois and disappeared on November 5, 1979. Last seen wearing a beige hooded jacket, a sweater, blue jeans, light brown suede shoes and a yellow gold necklace, she had long brown hair, gray eyes and freckles. Initial inquiries produced few leads and the case went cold, leaving her family without answers.

Attention later turned to Bruce Lindahl after his 1981 death. Investigators found photographs at his residence that included images identified as Deborah McCall, making him the prime suspect in her disappearance. Lindahl has since been linked by DNA to other cold case murders, but Deborah’s body has never been recovered and she remains the only one of his suspected victims still missing.

What can anyone who knew Deborah, or who remembers Downers Grove in 1979, add that might help resolve her disappearance?
