Michelle Martinko was found stabbed to death in her car outside a local mall in December 1979. After ruling out those who knew her, the Cedar Rapids Police Department started to suspect that the 18-year-old Iowa teen had been stabbed 29 times by a stranger. She was not robbed, despite having $186 on her, and was not sexually assaulted.
"She was nervous about going out to the mall by herself," her friend, Tracy Price, told CBS's 48 Hours in December 2023. "She had told someone that she felt like she was being followed."
