Police say a registered sex offender is the focus of an investigation into the death of 14-year-old Amber Dubois, whose skeletal remains were discovered in a remote, rugged area north of San Diego.
Escondido police said Monday that 30-year-old John Albert Gardner III remains a suspect after Amber's bones were found near Pala, more than a year after she disappeared near her school.
Police did not elaborate in a statement. They say the crime scene is being processed after the remains were discovered early Saturday.
Gardner pleaded not guilty last week to murdering 17-year-old Chelsea King of nearby Poway, a potential death penalty case. He also pleaded guilty to attempting to rape another woman in December.
