Authorities are still investigating the circumstances surrounding the death of former Notre Dame star Louis Nix, and some new details surfaced in the case on Monday.

Nix, who was 29, was found dead after his car was pulled out of a pond on Saturday in Jacksonville. He had been reported missing by his family several days prior. Nix’s girlfriend said he was driving in the car with another man, but investigators have yet to confirm or deny that.

Jacksonville reporter Ben Becker spoke with Nix’s mother on Monday, and she said police told her they do not suspect foul play. She said investigators believe it was an accident and that “something may have distracted (Nix and he) lost control and went into the pond.”
