Louisiana Tech officials say the family of Tyrone Duplessis has released information showing the former Bulldogs running back died from a massive heart attack. According to his father, George Duplessis Jr., Duplessis completed a workout on Feb. 1 before returning to his off-campus apartment in Ruston. He spent the evening at dinner with his fiancee. Early the next morning, George Duplessis says his son sprung up in bed, pounded himself in the chest and fell backward.
