An infant is missing from the Long Beach residence where three people were found with gunshot wounds Saturday evening, police said.
Just before 6 p.m., officers responded to reports of a shooting in the 100 block of West 51st Street, said Long Beach Police Department spokeswoman Marlene Arrona.
Three people -- a woman and two men -- were taken to a hospital in critical but stable condition, but a 3-week-old girl, Eliza Delacruz, was missing from the residence, Arrona said.
Investigators believe the adult male who shot the three victims also left with the infant, who weighs 10 pounds.
No amber alert has been issued as of 10 p.m. Saturday, and investigators are waiting to interview the three shooting victims.
