Will Smith shooting: Everything we know as of Sunday night

The suspect charged with fatally shooting New Orleans Saints defensive end Will Smith once sued a retired police officer, who had dinner with Smith shortly before he was shot Saturday night, authorities said.

The officer, retired Capt. William Ceravolo, was not on the scene of the crash, and police are investigating whether Smith's dinner companion played a part in the motive for the shooting, but investigators "don't have any info that links the incidents at this time," New Orleans police spokesman Tyler A. Gamble told NBC News.
