Police are investigating the death of an infant who was discovered in a dumpster in Azusa on Thursday afternoon, officials said.
The death was first reported just before 3:45 p.m. in a residential neighborhood in the 600 block of East 5th Street, Azusa Police Department Sgt. Jason Poulos said.
Police received a report that a baby had been left in a dumpster behind a row of condominiums, Lt. Robert Chives said.
"Officers located a female newborn inside one of the dumpsters," he said. "At that time, the newborn was motionless and there were no signs of life."
Paramedics rushed the infant to a hospital, but medical staff was unable to revive her, Chives said. The child was pronounced dead at 4:37 p.m.
Police determined the family of the baby lived in the immediate area, the lieutenant said.
"We've contacted and interviewed family members," he said, adding that they appeared cooperative.
Neighbors told KTLA the mother of the baby had only lived in the neighborhood a short time.
Savannah Larson said she and her husband heard screaming shortly before 4 p.m.
"I heard someone saying, 'Why did they have to throw the baby away,'" she said.
Jessica Spencer said she heard frantic calls for help from family members.
"They wanted to know where the baby was. Then the next thing I heard was, 'the baby is dead.' Then I heard that the baby was in the dumpster."
No arrests had been made and no further details were available as police continued their investigation Thursday night.
