Cleveland (AP) -- Authorities say they have confirmed a total of at least 11 victims whose remains were found in the Cleveland home of a registered sex offender.

The Cuyahoga County Coroner's Office said Wednesday that a skull found in a bucket in Anthony Sowell's basement belonged to a body they have not yet found.

Authorities also say they have identified one of the victims as 53-year-old Tonia Carmichael, who disappeared a year ago.

Police chief Michael McGrath says her remains were buried in the back yard and had marks indicating she was strangled.

Carmichael's daughter Markiesha Carmichael-Jacobs says her mother struggled with drug addiction and frequented Sowell's neighborhood.
