Authorities Monday offered a $50,000 reward for information that leads to an arrest and conviction in the slaying of a 15-year-old girl who was shot as she waited with her mother outside a hamburger stand in South Los Angeles.

Hannah Bell was fatally wounded about 9 p.m. Friday at a Best Burger hamburger stand near 77th Street and Western Avenue and died at a hospital, the Los Angeles Police Department reported.

Authorities scheduled a 10 a.m. news conference at the crime scene to announce the reward and seek public help in solving the killing. The slain teen’s mother was among those expected to be on hand.

A male suspect wearing a black hoodie was last seen leaving the location on foot, southbound on Western Avenue, said LAPD Officer Mike Lopez. Police said they did not have a motive for the killing.

The reward was offered by the Los Angeles City Council for information leading to the identity, arrest, and prosecution of the suspect or suspects responsible for the killing. Anyone with information on the crime was urged to call (877) LAPD-247.
