Teenager Identified as Killer in 1978 San Jose Teacher Murder

Decades after the 1978 murder of teacher Diane Peterson at a California high school, the case was solved when the killer, Harry Nickerson, who had confessed to a family member shortly after the crime, was identified. Nickerson, who died by suicide in 1993, had a history of violence and was linked to the case through a confession, ending a nearly 50-year-old mystery.
