New Orleans' police chief says investigators don't have any evidence that former New Orleans Saints defensive end Will Smith and the man accused of killing him knew each other, or that Smith was targeted.
Superintendent Michael Harrison says that so far, it appears just to be an accident turned violent.
At a brief news conference Sunday, he would not say whether 28-year-old Cardell Hayes claims he shot Smith in self-defense. He says he doesn't want to say anything that might compromise the police investigation or weaken the case against Hayes.
He says Hayes shot Smith and Smith's wife during an argument after Hayes' Hummer rear-ended Smith's Mercedes about 11:30 p.m. Saturday.
Harrison says Smith's wife was shot once in the leg.
