Christopher Walker, 26, was shot and killed on October 30, 2014, while sitting on the patio at Fair Oaks Burger at Fair Oaks Avenue and Calaveras Street in Altadena. The attack happened around 4:30 p.m. when a light-colored sedan pulled up, a person exited and fired multiple shots at Walker, then the vehicle fled. No words were exchanged before the shooting.

Walker had a steady job in marketing and had returned to California from Arizona with his girlfriend and two children as he worked to rebuild his life after a troubled youth. He had been involved with gangs as an adolescent and was known as C Madness; investigators reported the shooting was likely gang-related. Witnesses saw a dark gray four-door car with at least two occupants leaving the scene. No arrests have been announced and the Los Angeles County Sheriff’s Department continues to seek information.

Did anyone in the area on October 30, 2014, see the vehicle or the person who got out of the sedan?
