Homicide investigators continue Friday to look into the death of a San Diego woman who was found on a Lemon Grove street with a fatal head wound.
The woman has been identified as Jennifer Rene Krajnak, 30. She was a resident of San Diego County, according to the San Diego Sheriff's Department.
Krajnak was found by two deputies patrolling the 7600 block of Pacific Avenue, near Broadway and Buena Vista Ave early Thursday. Possible evidence in the case indicating that she may have been shot was found later in the day.
"There was a shell casing found at the crime scene, however, it is unknown whether or not it was related to this incident," Lieutenant 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.
Krajnak had apparently filed a restraining order against a Marine in 2010 on domestic violence allegations, according to NBC San Diego. That agency says Krajnak claimed to have been hit, choked and kicked by the man-- but later vacated the order.

"[Deputies] saw a woman lying on the side of the road and stopped to check on her," he said. "They found that she had 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.
No suspect has been named in the case.
