A neighbor says he heard the cries of a 9-month-old boy who authorities believe later starved after his mother died of an apparent overdose inside their Pittsburgh-area apartment.

William Gonzalez tells the Pittsburgh Tribune-Review he heard the cries of little Casey Kessler when he went in and out of the apartment building in Millvale but didn't think much of it at the time.

Gonzalez says he feels horrible.

Police say the dead woman's brother found the bodies early Friday morning when he went to check on his sister, 22-year-old Sara Kessler.

Assistant Allegheny County police Superintendent James Morton says Kessler may have died a week or two earlier. She was found on her bed and her son in the living room. There was no sign of foul play.

Autopsies are planned for Saturday.
