Arkansas State Police say Ty Keith, 22, was not in a vehicle at the time he was fatally injured.
State police say Keith got to the location on the rail tracks with some other people.
No further details were released.
Keith’s lawyer in his case involving a national fraternity said Keith’s death was a tragic accident.
Keith was to be in court next week for his lawsuit against Sigma Tau Gamma national fraternity and a faculty adviser at Southern Arkansas University.
Keith’s lawsuit alleged that fraternity members beat him so badly that he spent 11 days in a hospital, had to have kidney dialysis and required skin graft surgery.
He had reached a settlement with fraternity members.
