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.
Chitwood said there were no gunshot or stab wounds to the bodies but the son found scarves wrapped around each of their necks. Also discovered on scene were checks written to each of the couple's three children and several notes, some of which appeared to be written in Hindi, according to police. The couple appeared to be of Indian descent, Chitwood said.
