Ex-Iowa offensive lineman Kyle Calloway was struck and killed by a train while jogging Saturday in Tucson, Arizona. He was 29.

?We are all stunned and very saddened to hear of the tragic accident claiming the life of Kyle Calloway,? Iowa coach Kirk Ferentz said in a team release.  ?Our heartfelt condolences and prayers go out to Kyle?s family and to those who knew him.  He was a valued and respected member of our program.?

According to a release by the Tucson Police Department, Calloway was jogging westbound on and off railroad tracks east of South Rita Road and East Old Vail Road when he was struck from behind by a westbound train.

?That was what he did for exercise,? said Kyle?s father, Ed Calloway. ?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.?
