A Man Running, and a Marlboro

Investigators had little to work with. No weapon was found. Michelle's car keys were missing. Witnesses said they saw a man fleeing the area around the time she vanished. Near her body lay a Marlboro cigarette butt and several burnt paper matches, and the butt was preserved. In 1976, nobody could pull a name out of it. The killing drew intense media coverage and stayed unsolved for three years.
