Witnesses told investigators that shortly before Lavoie was shot, he was in a white Honda Civic that was being followed by the pickup truck. The two vehicles were headed west on Northwest 33rd Street, about a half-mile west of North Andrews Avenue.
As the vehicles approached the stop sign at Northwest 15th Terrace, Lavoie jumped out of the Civic to confront Anthony, the driver of the Tacoma, the Sheriff's Office said. Lavoie's girlfriend, who was driving the Civic, told investigators that Lavoie felt that Anthony was driving too close to their vehicle.
Witnesses told investigators Lavoie argued with Anthony, tried to open the door of the Tacoma and was seen reaching in through the driver's side window. Fearing for his safety, Anthony took out his weapon and fired a fatal shot, authorities said.
Anthony waited at the scene, was interviewed by detectives and later released. He has a state firearms license and a concealed weapons permit, said Sheriff's Office spokeswoman Keyla Concepcion.
At the scene, both vehicles sat bumper to bumper, just inches from each other. More than 100 residents of the adjacent Parkridge East Mobile Home Park watched from behind a fence. Many gave conflicting stories, but most remember hearing profanity-laced shouting before the gunshot.
"I heard some screaming and then a loud pop. When I looked over, the man was just laying there," said Cesar Garcia, 32.
"Something upset the victim enough to provoke him to get out of his car," Concepcion said. "Whatever it was, was it really worth having somebody dead right now? Was it really worth it for him to lose his life?"
