According to a news release from the City of Tucson Police Department, Calloway was "jogging westbound on and off the tracks when he was struck from behind by a westbound train."
Calloway's father told The Gazette that Kyle liked to run for exercise.
“That was what he did for exercise,” Ed Calloway told The Gazette. “He liked to run and it had rained the day before and the area where he ran was muddy, and so he was going back and forth across the tracks to get out of the mud.
“The longer version is at our old house, the train on the right side of the tracks went east, and the train on the left tracks went west. Our presumption is this train was on the opposite side that he was used to so he got on to the side so the train would have been coming at him from the front. We think that he got confused because the train somehow had been slopped over and was going in a different direction that he was used to. We don’t know, we’re just assuming that’s what happened.”
Calloway was 29 years old. The offensive tackle never saw regular season action with the Bills as he was released on August 30th of his rookie season. He'd go on to play in the UFL for the Hartford Colonials and spend time in the 2011 preseason with the Baltimore Ravens.
