OAKLAND (CBS/BCN) -- Police are searching for clues in the death of a former stripper whose nude body was found in the Oakland hills at the entrance to a bike trail.

Authorities have identified the woman found Friday as 40-year-old Jill Marie Abbott of Richmond.

An autopsy Monday failed to determine a cause of death. Police said they are waiting for toxicology test results to come back to help in their investigation.

The Oakland Tribune reports that a friend last spoke with Abbott on Thursday morning after she had sought help for a panic attack Wednesday night at a Richmond hospital.

Investigators are trying to determine her whereabouts between then and the time her body was discovered Friday morning.
