Former NFL star Marion Barber III was working on a trucking venture, writing a book, and had been committed to raising awareness for social injustice before his tragic death this week ... his attorney tells TMZ Sports.
Zoltan Papp, who represented Barber in his legal case following his 2019 arrest, says he and the former Dallas Cowboys running back were close friends -- and the 38-year-old had given him no signs recently that he had been in any kind of trouble.
"There was no indication of any desire to end his life, if that is what happened," Papp said. "Everything was about the fight to bring justice and to help others. Marion is a person who at his core is pure good."
