SAN DIEGO (AP) - California Gov. Arnold Schwarzenegger has signed legislation that will lock up some convicted sex offenders for life.

Chelsea's Law was signed Thursday. It's named for 17-year-old Chelsea King, who was murdered in San Diego in February.

A convicted child molester was sentenced to life in prison without parole less than three months later for killing King and 14-year-old Amber Dubois.

Schwarzenegger signed the bill at San Diego's Balboa Park alongside Chelsea's parents, Brent and Kelly King, and the sponsor, Republican Assemblyman Nathan Fletcher of San Diego.
