Melissa Anne Smith was 17 and a high school senior when she left a pizza parlor in Midvale, Utah, on the evening of October 18, 1974. She intended to stay at a friend’s house but began walking home after plans changed and never arrived. Her father was Midvale police chief Louis Smith.

On October 27 deer hunters found her nude body in a mountainous area in Summit Park. An autopsy determined she had been brutally beaten and strangled, and evidence suggested she may have been kept alive for up to seven days after her abduction. Her disappearance was one of several around that time that raised fears of a serial predator.

The man later identified as responsible was Ted Bundy; before his execution he confessed to her murder. Bundy had been first arrested in 1975 on an aggravated kidnapping and attempted criminal assault charge, an arrest that led investigators to suspect him in multiple unsolved homicides across several states.

Did anyone in the Midvale or Summit Park area in October 1974 recall unusual activity or a lone vehicle near the pizza parlor or along the route Melissa would have taken?
