Feb. 28 (UPI) -- Former Notre Dame Fighting Irish football star Louis Nix III was found dead Saturday after being reported missing three days earlier, his family said. He was 29.
Nix's family reported him missing on Wednesday to police, ESPN and the Florida Times-Union reported. After multiple days of searching, the Jacksonville Sheriff's Office issued an update on social media Saturday night that Nix had been located. The update didn't reveal Nix's condition or where he had been found.
Nix's mother said it remains unclear how or when he died.
"It's all a mystery right now until they give me more information about what happened," she said.
Notre Dame head coach Brian Kelly honored Nix on Sunday by posting a tribute video on Twitter.
Nix was injured in a shooting in December while at a gas station near the Jacksonville airport. He said on social media at the time that he spent 10 days in the hospital after a bullet ricocheted off his sternum and went into his lung.
Nix, who helped guide the Irish to the 2013 BCS National Championship Game, starred for three seasons at Notre Dame. During the team's undefeated regular season in 2012, he anchored the defensive front and led all Notre Dame defensive linemen with 50 tackles.
The Houston Texans selected Nix in the third round of the 2014 NFL Draft. He never played a game for the Texans due to multiple knee injuries.
Nix later appeared in four games with the New York Giants in 2015. He also spent time on the practice squads of the Jacksonville Jaguars and Washington Football Team.
