Authorities say they're still investigating the death of a Cottonwood woman late last year.
They say 61-year-old Pamela Dee Shepherd was found dead in her car in a closed garage of her locked home on Nov. 21.
Police were called to the house after Shepherd failed to show up for work the previous day.
Investigators say it appears there was some kind of struggle inside the home and her body may have been placed in the vehicle afterward.
They say several pieces of evidence have been collected at the scene and are being analyzed at the Arizona Department of Public Safety crime lab.
The autopsy report for the cause of death hasn't been released yet, but police say the death is considered suspicious and they have an investigative lead.
