A witness told The Times-Picayune on Thursday that she saw the driver of a blue Infiniti sedan yelling at McKnight, who appeared to be apologizing, as they stood in the middle of a busy intersection. The man who was yelling — later identified as 54-year-old Ronald Gasser — then shot McKnight several times, she told the newspaper. Gasser stood over the victim and said, "I told you don't you (expletive) with me," and fired a final shot, the witness said.



"The only thing we know right now, everything else is conjecture, is that Mr. Gasser did in fact shoot Mr. McKnight," Normand said. He added that Gasser remained at the scene and relinquished his weapon to responding officers. Normand says Gasser is in custody and being questioned. No other gun was found outside the vehicles, but cops had not yet searched the cars and won't until a search warrant is issued.
