(CNN) -- A 3-month-old boy was killed Sunday during a triple-shooting in California, according to the East Palo Alto police department.
The incident left the child's mother and father wounded with injuries that are serious but not life-threatening, police said in a statement.
The victims had been attending a baby shower and left shortly after midnight Sunday. As they were leaving, two unidentified men in dark clothing fired multiple shots into the vehicle, wounding the adults and killing the infant.
Another son, who is 3, was uninjured.
