Los Angeles police have announced a $50,000 reward for a man suspecting of killing a worker at a medical marijuana dispensary.

Detectives on Thursday said they are looking for 27-year-old Raymond Lemone Easter, a suspected gang member believed to be one of three people who robbed the Echo Park dispensary June 24.

After ransacking the business and stealing money and marijuana, the robbers shot store worker Matthew Butcher and a security guard. Twenty-seven-year-old Butcher died from his injuries and the guard is recovering.

Another suspect in the case, 31-year-old Daniel Hinton, has been charged with murder and attempted murder.

Police are also looking for information about the third suspect and the driver of a getaway car.
