A 14-year-old Vallejo boy has pleaded not guilty to charges that he kidnapped a 65-year-old woman at gunpoint from a shopping center parking lot and raped and beat her.

The Times-Herald of Vallejo reports that Kaviar King entered the plea on Monday to attempted murder, torture, kidnapping, rape and other counts in the Nov. 15 attack. He has been charged as an adult.

Authorities say King abducted the woman at dusk and forced her to drive several miles away, where he sexually assaulted and beat her before leaving her unconscious and duct-taped in a ditch.

As police were investigating, they say the woman's family received a call demanding money for her return. King was arrested after allegedly returning to the scene of the abduction hours later.

Police have described the attack as random.
