FAIRFIELD — A 70-year-old former death row inmate was arrested Wednesday on suspicion of killing his 89-year-old mother in Vallejo.
Dennis Stanworth called Vallejo police shortly before noon and said he had killed his mother, according to Vallejo police. Officers responded to the 2500 block of Marshfield Road and Stanworth directed them to an area on the property where a woman was found dead, police report.
Police obtained a search warrant for the home and secured crime-scene evidence. Stanworth was interviewed and then arrested on suspicion of murder. He was booked into the Solano County jail.
The victim is believed to be Stanworth’s mother, Nellie Turner Stanworth. Confirmation of the victim’s identity is pending.
According to police, Dennis Stanworth has a long criminal history that includes two murder convictions for which he pleaded guilty and was sentenced to death in 1966 for kidnapping, sexually assaulting and shooting two teenage girls in Contra Costa County.
The victims were Caree Lee Collison, 14, and Susan Muriel Box, 15. The attack occurred Aug. 1, 1966. Box likely died instantly after being shot in the head, according to court records. Collison was alive when the girls were found two days later, but was comatose and never regained consciousness. She died several days later.
The attack on Box and Collison occurred amid a string of violent sexual assaults committed by Stanworth, according to court records.
Stanworth’s death sentence was reversed and he was sentenced to life in prison. He was later paroled and required to register as a sex offender.
The Vallejo incident remained under investigation Wednesday. Police are scheduled to provide an update at 11 a.m. Thursday at the Vallejo Police Department, 111 Amador St.
