Officer Brad Fox was shot in the head while responding to a call of a hit-and-run.
Officer Brad Fox would have celebrated his 35th birthday on Friday.
The Plymouth Township police officer was killed in the line of duty while responding to a call for a hit-and-run Thursday afternoon at Conshohocken Road and Ernest Station Road in Plymouth Township, Montgomery County.
Fox was shot in the head.
"There are just no words that can begin to express the magnitude of this tragedy, " said Montgomery County District Attorney Risa Vetri Ferman at a Thursday night press conference.
"I think we're all in shock. This is the very first time that the Plymouth Township Police Department has had to deal with an officer killed in the line of duty," said Ferman.
Fox had a little girl and his wife is pregnant with their second child.
"Officer Fox served two tours of duty in Iraq. He put his life on the line day in and day out. Men around him lost their lives. He was able to come back from that service, come back to the comfort of his country and to lose his life so senselessly today, there are just no words to explain how horrific it is, how senseless it is," Ferman said.
Fox had been with the Plymouth Township police department for seven years, said Chief Joseph Lawrence, who called the officer a "hero."
He had just graduated from the Philadelphia K-9 school.
His fellow officers gathered outside the emergency room Thursday night as Fox's body was transported to the Medical Examiner's Office.
According to sources close to the investigation, the suspect was shot in the chest and died near the scene.
A 9mm Beretta was found next to the suspect's body. "There is no gunman out on the street. There is no imminent danger to anyone out there," said Ferman.
Fox's K-9 officer was shot, and survived.
The District Attorney did not release any further information about the exact circumstances leading up to Fox being shot.
Ferman said the investigation is ongoing.
