Police have arrested a man suspected in the slaying of a female relative who was found decapitated at a home in Northern California. Police say officers responding to reports of a possible homicide discovered the victim’s body Thursday afternoon at a home in Santa Rosa, north of San Francisco. Officials say the woman's head was not at the residence. Investigators identified a 24-year-old male relative of the woman who was seen leaving the crime scene on foot as a suspect. He was arrested Friday morning in San Francisco. Officials say the suspect had recently been released from prison after being incarcerated for assault with a deadly weapon.
