San Francisco police are investigating a homicide after a woman was found injured in a homeless encampment in the Mission District last week and later died at a hospital, authorities said.

Police responded to a call for welfare check after a woman was found unresponsive at a homeless encampment on the 2700 block of 16th Street near Treat Street around 6:30 a.m. Friday, said Officer Albie Esparza, a police spokesman.

They discovered the victim, later identified as 33-year-old Allison Sparrow, suffering from unknown injuries, Esparza said. She was taken to a nearby hospital, but later died.

Few other details were released about the incident including how Sparrow incurred the injuries, a possible motive or suspect description, but Esparza said homicide detectives had been assigned to the case.

Anyone with information about the incident was encouraged to contact police at (415) 575-4444.
