The boy was wounded in the torso Friday night and remained hospitalized in critical condition Saturday, the San Bernadino Sun reported. A man in his 50s was shot in the arm and a man in his 30s suffered a bullet graze, the newspaper said. The victims' relationship was unclear.
Pasadena police Lt. Jason Clawson said the shots were fired from in front of the home about 9 p.m. PDT Friday.
"The rounds penetrated a residential structure, a garage area, where the victims were," he said.
Three suspects were being sought but none had been arrested and a motive had yet to be determined, Calatayud said.
The shooting took place on the same block where a teenage boy was wounded slightly in a shooting Wednesday, the Sun said. No arrest had been made in that shooting either.
