Neal Christopher Perez-Melo, 27, was shot in the early hours of April 1, 2016, in the Visitacion Valley neighborhood of San Francisco. Witnesses said the shooting happened at about 2 a.m. outside a residence on Teddy Avenue; Perez-Melo was struck multiple times in the torso and was taken to hospital by three men in a silver BMW. He died a few days later, and investigators treated his death as a homicide.

The Teddy Avenue location drew attention because it was the site of a police raid connected to Stanislav Petrov, who had been involved in a November 2015 incident where he was beaten by Alameda County deputies. Authorities say Perez-Melo’s shooting was not connected to Petrov’s case. The FBI and the San Francisco Police Department opened an investigation, but the case remains unresolved.

Anyone with information about the shooting or who saw activity around Teddy Avenue that night is asked to come forward.
