Vital Statistics at Time of Disappearance
Details of Disappearance
On March 2, 1985, Peggy Alt left her home on Williams Creek Road in High Ridge on foot, two days before her 18th birthday. No one reports ever seeing her again. Peggy’s father, Robert Alt, reported her missing to the Jefferson County Sheriff’s Office the day she disappeared.
An investigation into Peggy’s disappearance was canceled 11 days after it started, for unknown reasons. Her case was reopened in 2011. Her boyfriend at the time, a man who was 10 years older than Peggy, was interviewed in depth and denied any knowledge of what happened. The grounds surrounding the family’s former home was searched using cadaver dogs. When officers found a cistern, they dug it up and cleaned it out, but found no evidence.
Peggy was a senior at Northwest High School when she went missing. There’s no record of any activity with her Social Security number. Foul play is suspected in Peggy’s disappearance.
