A 9-month-old boy found dead in a Pittsburgh-area apartment is believed to have starved after his mother died of an apparent overdose.
The woman's brother found the two dead early Friday morning when he went to check on his sister.
Sara Kessler, 22, had not been heard from for several days, Assistant Allegheny County police Superintendent James Morton said.
Morton said Kessler may have died a week or two earlier.
She was found on her bed, with the son, Casey, found in the living room.
He said there were no signs of foul play.
'It's a very sad situation in there,' Morton told reporters outside the apartment in Millvale, just across the Allegheny River from Pittsburgh.
'It seems like he [the infant] tried to survive but there was no food or anything for him to have.'
'It looked like he was trying to get around somehow by himself for who knows how long.'
The woman's mother died of natural causes in the same apartment in November, Morton said.
Police suspect the woman died of a drug overdose, and needles were found all over the apartment.
A former resident of the building told CBS Pittsburgh that Kessler was a drug addict and said that the family had tried to get her help many times.
