The Story of a Wannabe Serial Killer

The episode recounts the chilling 2013 double murder of Claudia Morpin, 67, and her husband Oliver 'Chip' Northup, 87, in Davis, California—a quiet college town known for its safety and community spirit. The couple, beloved members of the Unitarian Church and deeply involved in local life, were found brutally stabbed 67 and 61 times respectively, with disturbing evidence suggesting the killer conducted macabre experiments on their bodies, including placing a phone in Claudia’s abdomen and a glass in Chip’s stomach. The investigation initially focused on family members, particularly Chip’s son Robert and his sons, due to access and suspicious behavior, but no conclusive evidence emerged. The case went cold until a 17-year-old student, Alvaro Garibe, anonymously reported that his best friend, 15-year-old Daniel Marsh, had confessed to the murders. Daniel, once a celebrated child hero for saving his father’s life at age 10, was revealed to have a deeply troubled past marked by parental divorce, self-harm, suicide attempts, and violent fantasies. During a grueling interrogation, Daniel’s chillingly detailed descriptions of the murders and his own murderous impulses—along with his calm demeanor—led investigators to believe he was the perpetrator. Found mentally competent, he was convicted of two counts of first-degree murder with multiple enhancements and sentenced to 25 years to life. The case remains a haunting example of how a child once hailed as a hero could descend into darkness, raising profound questions about mental health, justice, and the unpredictability of evil. Despite legal changes that may allow for early parole, Daniel remains incarcerated as of 2037, with his first parole eligibility in June of that year.
