Clarnell Elizabeth Strandberg, 52, was murdered on April 20, 1973, in Aptos, California. Her son, Edmund Kemper III, whose relationship with his mother is described as deeply troubled and marked by frequent arguments and psychological abuse, returned to her home after time in Alameda and attacked her while she was in bed reading. He struck her on the head with a hammer, strangled her, then decapitated and mutilated her body. Kemper later said he resented his mother and feared she would suffer consequences for his earlier crimes; he admitted the murder and detailed post-mortem actions, including placing her severed head on a shelf and removing her left hand, which he linked to symbolic punishment.

After killing Strandberg, Kemper invited her friend Sally Hallett to the house and killed her as well, then left the area and eventually surrendered in Pueblo, Colorado. He confessed to multiple murders, pleaded guilty at trial, and was sentenced to life imprisonment without parole. Does anyone have additional information about Strandberg’s life in Aptos or remember her before 1973?
