UPPER DARBY, Pa. (CBS) – Police in Upper Darby are calling the death of a 4-month-old boy a homicide after a recent autopsy report revealed new information in the case.

“The tragedy is a four-month-old is dead and no one is cooperating with the investigation,” said Upper Darby Police Superintendent Michael Chitwood. He says someone in a home at 126 North Fairview Avenue knows what happened to baby Jaden Jones, who’s death last November was just ruled a homicide in the beginning of May. The cause of death, according to Chitwood, is cranial trauma.

“It could be something very similar to shaking a baby very hard,” said Chitwood.

Police were called to the home at 4 a.m. November 6th for an unresponsive infant. Four people were reportedly home at the time.

“The mother, a family friend, a 16-year-old child and a 21-year-old,” said Chitwood.

A man who identified himself as an uncle spoke to Eyewitness News reporter Robin Rieger through the door about the family’s reaction to the recent homicide ruling

“I’m just saying its like all news to us,” he said. “It’s very disturbing. I don’t know. Her lawyer told her not to speak to anybody.”

Chitwood says no one in the home is cooperating with the continuing police investigation.

“It’s unconscionable that someone could kill a four-month-old baby, is what they did. My hope is that who’s ever responsible for this child’s death, their conscience is bothering them,” said Chitwood.
