Police are hoping that a sketch will help them identify a woman whose body was found inside a trash can on a road near an upscale neighborhood in Pleasanton.

Police on Wednesday released an artist's rendition that shows what the woman may have looked like.

The woman is believed to be between 25- and 40-years-old with shoulder-length dark hair, 5-feet 6-inches tall and weighed about 130 pounds. She also did not have any tattoos or identifying marks.

The woman also was wearing an Old Navy shirt and pajama bottoms when she was discovered on May 24.

Lt. Jeff Bretzing says police are still waiting on toxicology reports after a preliminary autopsy could not determine the woman's identity and her fingerprints could not be traced through state motor vehicle records.

Police say the woman's description also has not turned up on any missing persons reports.
