Former NFL defensive end Will Smith has died following reports he was shot in New Orleans on Saturday.
A road traffic incident on Sophie Wright Place in the city led to a heated exchange in which a 34-year-old male is confirmed to have been killed.
A police spokesman at the scene said: "The 34-year-old male victim's vehicle was travelling eastbound on Sophie Wright Place when his vehicle was hit in the rear by a Hummer H2.
"The collision caused the victim's Mercedes G63 SUV to strike the rear of a Chevrolet Impala who was travelling along with the victim.
"The victim and the driver of the Hummer exchanged words, at which time the driver of the Hummer produced a handgun and shot the male victim multiple times and his 34-year-old wife twice in the right leg.
"The male victim was pronounced dead on the scene.
"His wife was transported to a local hospital.
"The 30-year-old driver of the Hummer is now in police custody and is being questioned by detectives."
Local media identified Smith as the victim, with New Orleans Saints senior vice-president of communications Greg Bensel subsequently tweeting: "A senseless and tragic loss.
"Our thoughts are with Will Smith - his wife Racquel - his children William, Wynter and Lisa."
Smith spent 10 seasons with the Saints, who selected him with the 18th overall pick in the 2004 NFL Draft.
He was a Pro Bowl selection in 2006 and helped the Saints win Super Bowl XLIV to cap the 2009 season.
The 34-year-old recorded 67 1/2 sacks and 324 tackles in 139 regular-season games with the Saints, who released him following the 2013 season after he sat out the entire year with a knee injury. Smith also was involved with the Saints' bounty scandal but had a four-game suspension overturned in 2012.
He signed with the New England Patriots in May of 2014, but was released soon after.
