PENN HILLS, PA (CNN) — A 4-month-old baby is dead in Pennsylvania after falling into a garbage bag.
Police say a relative left the baby on a bed for a nap as she tended to other children.
She said when she returned, the bedroom door was locked, most likely by another child.
The baby was found inside a garbage bag at the base of the bed.
Authorities say it appeared the infant suffocated.
County police have turned the case over to the district attorney for review.
