Two adults have been found dead of suspected drug overdoses after their 7-year-old daughter told school officials in western Pennsylvania that she couldn't wake them up.

Allegheny County police says the bodies were discovered Monday evening in the living room of their McKeesport apartment.

Authorities say a 9-month-old girl, 3-year-old boy and 5-year-old boy who were inside the home have been taken to a hospital to be evaluated.

Lt. Andrew Schurman says early indications are that the adults may have been dead for a day or two. He says they suspect the adults died from a drug overdose and that foul play is not suspected.

The bodies haven't been publicly identified.

Police say another fatal overdose happened on the same street earlier that day.
