It appears John Albert Gardner, a sex offender who murdered Amber Dubois and Chelsea King, did not kill anyone else, according to a task force.
The task force looked at Gardner's location records and compared them with missing-persons reports, according to a published report.
Lt. Dennis Brugos told the San Diego Union-Tribune that Gardner also talked freely with investigators but didn't confess to any more killings.
Gardner is serving a life sentence without the possibility of parole for kidnapping and murdering 14-year-old Amber Dubois last year and 17-year-old Chelsea King in February.
