That assistant D.A., Michael Donohue, was charged on Monday for the November 4th crash that left a 14-year-old boy with serious injuries.
Authorities say Jake Vantrieste was walking across Township Line Road at Bryan Street when Donohue slammed his Jeep Cherokee into him hurling Jake into the air.
"I thought he was actually dead. He wasn't moving for a while and then he moved," witness Frank Federovitch said.
As Vantrieste lay bleeding from a fractured hip and cracked skull, Upper Darby police say Donohue briefly got out of his vehicle on Agnew Drive, checked his Jeep, then sped off the wrong way down a one way street.
"Never once did he go back to see what had happened to the victim," Upper Darby Police Superintendent Mike Chitwood said.
Police quickly located the vehicle inside a garage in Roxborough.
Jake Vantrieste's mother is disgusted that Mike Donohue, a man whose job it is to prosecute crimes, would allegedly hit her son then flee.
"It's been a nightmare, it's been a complete nightmare. I don't want any parent to go through something like this," Dawn said.
Witnesses have come forward including a person was on the phone with Donohue when he allegedly got into the accident.
Donohue resigned on Wednesday, November 9th, a few days after the crash.
Donohue is out on $25,000 bail.
Jake Vantrieste, meanwhile, remains at Children's Hospital of Philadelphia and is expected to make a full recovery.
