The York County District Attorney's Office announced Friday that it won't file criminal charges over a fatal shooting during a road rage dispute.

That decision comes days after David W. Sunday Jr. took over as the county's DA.

At issue was the killing of James R. Weimert on Nov. 12. Investigators said Weimert was shot by Michael Yeaple during a fight after their vehicles collided at East Philadelphia and North Pine streets.

At least one witness described the shooting as a case of self-defense.

In a statement from its spokesman, Kyle King, the DA's office said it was basing its decision not to prosecute on a review of the police investigation, along with statements from officers and eyewitnesses, on cell phone video of the incident and on ballistics and medical reports.

"In light of all the evidence, facts and specific circumstances surrounding this incident, this office determined that the commonwealth would be unable to meet its burden of proof beyond a reasonable doubt," the DA's statement said. "An individual is not required to prove that they acted in self-defense. Rather, the law demands that the commonwealth prove beyond a reasonable doubt that an individual did not act in self-defense."

The office praised eyewitnesses "who came forward and provided the critical information necessary to make the appropriate decision under the law."

Police said Weimert was shot in the torso less than a half-hour after the 4:05 p.m. crash when an argument morphed into a physical fight. They said Weimert did not have a gun.

Yeaple was released after being interviewed by police. The county coroner's office ruled Weimert's death a homicide, but stressed that merely means it was caused by the actions of another person and does not indicate the death was a criminal act.
