James Goy, 50, and his wife, Lisa Goy, 48, were gunned down at close-range in the middle of their street in Plains Township on Monday after getting into a fight with their neighbor.
The gunman, 47-year-old Jeffrey Spaide, took his own life inside his home before police arrived at the scene.
During Monday's incident, authorities say Spaide had asked the pair to stop shoveling snow onto his property when the argument broke out.
The surveillance footage shows James throwing aside his tool and walking up to Spaide as he made a fist at him.
The Goys could be heard screaming at Spaide, calling him a 'mother******' and a 'p***y.'
Spaide could be seen retreating into his house as James screamed: 'I'll knock your a** out' and 'I'll make your life a living hell.'
Moments later, Spaide emerged from his home holding a pistol.The Goys, seemingly undeterred, continued to scream with Lisa yelling, 'Go ahead! Go ahead!'.
Spaide then fired several shots before eventually striking the couple. James could be heard screaming out while his wife collapsed in the street.
He then went back into his house and emerged moments later with an AR-15-style rifle, which he used to execute his neighbors.
'You should have kept your mouth shut,' he could be heard telling Lisa before he pulled the trigger.
Prosecutors said Spaide retreated into his home and paced back and forth in front of a window. They said he shot himself dead as the first police units responded to the scene.
