Bucks County prosecutors announced the autopsy findings for 27-year-old Tyler Roy and 28-year-old Christina Roy on Monday. They were killed April 30 in their Northampton Township home.
Authorities haven’t found any connection between the couple and their suspected killer, 26-year-old Daniel Mooney. He died of a drug overdose on the day the bodies were found by a house painter.

Authorities say Mooney gained entry through an unlocked door of a home on the 100 block of Kitty Knight Drive. Police believe that the murders happened sometime in the overnight hours.
“Our team is unequivocally convinced that he killed the victims and he acted alone. Both victims have been stabbed multiple times and both victims were shot. It’s clear there was a struggle in the upstairs of the home,” said Greg Shore with the Bucks County District Attorney’s Office.
Police said Mooney stayed in the house for an unknown period of time afterward.
“He struggled growing up. He had some mental health issues,” said Tom Walsh, who grew up with Mooney.MORE NEWS: Phillies Bring Back Bobby Dickerson As Infield Coach
