A taxi driver found his mother dead and his father unconscious in bed at their home behind the Upper Darby police station this afternoon, said Upper Darby Police Superintendent Michael Chitwood.
Detectives are still on scene combing for clues in what Chitwood labeled a "criminal death investigation" at the house on Winfield Avenue near West Chester Pike.
He said a taxi driver in his 20s received a gargled call on his cell phone from his father around 1 p.m. today, asking the young man to come home. When the man arrived, he found his mother, who was in her 40s, dead in bed. His father, who is in his 50s, was next to her breathing but unconscious, police said. Both were fully clothed.
The father was taken to Delaware Valley Hospital, where he remains in critical condition in a coma.
