VALLEJO (CBS SF) — The arraignment of a 14-year-old Vallejo boy charged with kidnapping and sexually assaulting a 65-year-old Solano County woman Thursday was continued until Nov. 26 in Solano County Superior Court in Vallejo.

Kaviar King is being prosecuted as an adult.

The Solano County District Attorney’s Office filed ten charges Friday afternoon against King that include attempted murder, torture, kidnapping for ransom, carjacking, robbery and sexual assault, Deputy District Attorney Andrew Ganz said.

King was booked at 6 a.m. Friday in juvenile hall and remains in custody.

Police said the woman was kidnapped at gunpoint in front of a retail business in the 100 block of Plaza Drive near the Gateway Plaza in Vallejo Thursday.

The woman was forced to drive her white minivan several miles, where she was assaulted, left unconscious and bound in duct-tape in a ditch. The suspect then left in the minivan.

There is no known relationship between King and the victim, Lt. Lee Horton said.

Passersby helped the woman in distress and called police and requested medical aid, Lt. Jim O’Connell said. The passersby also gave information that led to King’s arrest, O’Connell said.

Police responded around 6 p.m. and found the woman, a victim of an egregious physical and sexual assault, in the area of Hiddenbrooke Parkway and Interstate Highway 80 outside Vallejo city limits, O’Connell said.

One of the victim’s family members received a phone call from someone who demanded money in exchange for the victim’s return, O’Connell said.

Police arrested King when he returned to the Plaza Drive area, and he was found in possession of the victim’s property, a replica handgun and her minivan, O’Connell said.
