Authorities said the clerk, 39-year-old, mother-of-five Martha Sanchez, was working at the Happy Bargain discount store about 8:50 p.m. Tuesday when the robbery and shooting occurred in the 7400 block of Broadway — just two blocks from the LAPD's 77th Street Station.
The suspect fled on foot and a customer later found the mortally wounded Sanchez and called for help. She was taken to a hospital, where she died, authorities said.
Family members have called for the public's help in finding Sanchez's killer, saying she was a good, hardworking woman who cared deeply for her family.
"She was my role model. She was my best friend," daughter Gabriela Sanchez, 18, said during a news conference. "She was everything to me. And now she's gone."
Many of those who knew Sanchez gathered Wednesday outside the small store, saying they were saddened and shocked by the slaying.
