IONE, Calif. (AP) — Officials say a California serial killer who strangled and raped at least seven women was fatally choked himself in a state prison.
Roger Reece Kibbe, known as the “I-5 Strangler” in the 1970s and 1980s, was spotted unresponsive in his cell Sunday at Mule Creek State Prison southeast of Sacramento. His 40-year-old cellmate was standing nearby.
An autopsy showed the 81-year-old Kibbe had been manually strangled. The Amador County Sheriff’s Office is calling the death a homicide.
Kibbe was initially convicted in 1991 of strangling a 17-year-old who had run away from home in Seattle. Investigators at the time said Kibbe was also a suspect in six other killings.
In 2009, a San Joaquin County District Attorney’s Office investigator used new developments to connect him to the old slayings. Investigators secretly took Kibbe on multiple field trips from prison in hope that he would reveal the whereabouts of more victims.
