Edward Martin Cupp, a 43-year-old Caucasian man, was one of 25 men murdered during a killing spree in Sutter County, California, in 1971. Cupp was killed sometime between May 9 and May 13, 1971. The suspect, Juan Vallejo Corona, hired migrant farmworkers and then attacked them, often using a machete; the victims were buried in shallow graves across multiple orchards near Yuba City.

The crimes came to light after a peach farmer discovered a freshly filled hole on May 19, 1971; subsequent searches recovered 25 bodies with similar sharp-force injuries. Evidence tying Corona to the graves included receipts and deposit slips in some burials, bloodstained knives and a machete seized from his home, a ledger listing several victims, and witness reports of victims last seen in Corona’s pickup truck. Corona was arrested May 26, 1971, and charged with 25 counts of first-degree murder.

Does anyone have memories or information about Edward Cupp, his movements in May 1971, or how he came to be employed by a contractor in that area?
