The murder of school teacher Diane Peterson at Branham High School in San Jose, California, in 1978 has been solved, with Harry “Nicky” Nickerson, then a 16-year-old student, identified as the killer. Nickerson confessed to a family member shortly after the crime, and despite being a long-time suspect, he died by suicide in 1993 without facing justice. The case closure brings relief to Peterson’s family, who appreciated the persistence of investigators in seeking the truth after nearly five decades.
