The San Luis Obispo Sheriff's Office initially responded to a possible trespassing at a home on Friday and found the body of 77-year-old Jeanine Vore. They say she appeared to be the victim of murder.
Witnesses saw a car matching that of 18-year-old Kayonie Eliaz Mendibles' leaving the area. Authorities spotted the car later Friday night in nearby Pismo Beach and initiated a traffic stop.
Mendibles was arrested on murder charges and was booked into the San Luis Obispo County Jail.
