Police: Bullet Casing Found Near Woman Who Died in Lemon Grove

New details are emerging Thursday afternoon in the death of a woman who was found on the street in the early morning hours with head injuries, and later passed away.

The San Diego Sheriff's Department says they have yet to identify the woman who was found by two deputies patrolling the 7600 block of Pacific Avenue, near Broadway and Buena Vista Ave, but they have found some possible evidence in the case.

"There was a shell casing found at the crime scene, however, it is unknown whether or not it was related to this incident," Lietenent Glenn Giannantonio said in a press release.  

He added that the investigation is still in its preliminary stages and all the information at this point still needs to be verified by detectives.

The lieutenant said the woman was found with "trauma" to her head.

The woman was spotted at around 2 a.m., and immediately taken to Scripps Mercy Hospital.  She died about a half hour later, according to Giannantonio.
