The two victims killed Tuesday night in separate shootings have been identified.
Alfred Jonny Rodriguez, 40, of Los Angeles was shot in Florence-Firestone around 8:40 p.m. Tuesday, coroner's officials said.
Neighborhood residents first reported hearing fireworks, the L.A. County Sheriff's Department said.
When detectives went to check on the reports, they found Rodriguez lying in the street on the 1900 block of East 71st Street. He was pronounced dead at the scene.
About 2½ hours earlier, Juan Manuel Ibarra, 17, of Compton was walking outside with friends around 6:10 p.m. when two suspects approached.
One of the suspects shot Ibarra in the torso with a handgun, sheriff's officials said. He was pronounced dead at the scene in the 1300 block of Chester Avenue in Compton.
Investigations are continuing in both slayings.
