Homicide detectives responded to the store on the 10400 block of Inglewood Avenue shortly before 4:30 p.m., according to a sheriff’s news release.

A sign over the shop’s door read Floreria Mary & Party Supplies and said the business was celebrating its grand opening, footage from the scene showed.

A 57-year-old Hispanic woman working at the store was shot at least once in her upper torso, Lt. Joe Mendoza said.

She was transported to a nearby hospital, where she was pronounced dead.
