Linda Neukum was found critically injured near 300 Market Street in downtown San Diego late on the evening of December 23, 1981. A bystander encountered her staggering out of an alley around 11 p.m.; she collapsed and said she had been stabbed and that her attacker was a white male. Neukum was taken to the hospital and later died in surgery from numerous stab wounds.

Witnesses reported seeing a possible suspect running northbound on Second Street at the time of the attack. He was described as a white male, medium build, about 5 feet 8 inches to 5 feet 11 inches, with dark short or collar-length hair, wearing loose-fitting dark clothing. The suspect remained unidentified and at large.

If anyone was in downtown San Diego that night or has information about a man matching this description, please come forward with what was seen or heard.
