Carter accused Jennings of shining a light into his eyes as he was returning home, and went inside to fetch a .380-caliber Ruger semi-automatic handgun.
Carter went back outside and parked his car up on Jennings' lawn with his lights on full beam, according to a criminal complaint seen by Philly.com.
A heated argument then started and Carter shot Jennings in the head, knocking him to the ground, the complaint says.
Carter then shot Jennings in the head a second time while standing over his body, as his distraught wife watched from inside the house, it is alleged.
Carter admitted shooting Jennings but says he acted in self defense after Jennings advanced on him with a knife.
Police say they recovered two shell casings from the scene - one from Carter's yard, and one from beside Jennings' body.
They also recovered a knife, though it is not clear where the weapon was found.
