Though he developed a following far beyond Southern California, his death last week struck a particularly painful chord among residents of the Crenshaw District, where he grew up. His clothing store on Slauson Avenue in South Los Angeles, The Marathon Clothing, had become a potent symbol of local success and black entrepreneurship, a theme he addressed regularly in his music. His fans clung to lyrics that melded familiar rap bombast with exaltations about self-discipline and long-term financial planning, a break from a music culture that often emphasizes flashy spending.

The store transformed into a makeshift memorial on March 31 after Hussle was gunned down there over a “personal dispute,” according to the Los Angeles Police Department. The suspect, Eric Holder, was apprehended by authorities two days after the shooting.

For days outside the store, fans prayed, lit candles and left hand-written letters addressed to Hussle. One of the mourners was Candace Cosey, 32, who remembers him as Ermias from their time attending Hamilton High School together in the early 2000s, a magnet school on the West Side of Los Angeles. She recalled how Hussle would sell mix CDs to her and others at school, and how he later started selling music in the neighborhood out of his trunk.

She came close to tears as she pulled out a picture of him from the high school yearbook. “If you grew up here, you either knew him directly or you knew someone who knew him,” she said.

Even as his career took off, Hussle remained approachable and “big hearted,” she said. As he amassed fame and wealth, he continued living modestly while making investments in businesses in the neighborhood. And he could be very generous. When a colleague passed away several years ago, Ms. Cosey approached Hussle’s team to see if he could help with the funeral expenses. He contributed several thousand dollars, she said.
