Greensboro, NC -- North Carolina A&T State University's athletic director said no trainer was present during track tryouts where a student collapsed and later died.

Wheeler Brown said 20-year-old Jospin Milandu was a sophomore walk-on trying out for track. He could not confirm why no trainer was present, but said school policy requires a trainer attend tryouts and other events.

Brown also said he did not know whether Milandu had taken a required physical test before trying out. He said university investigators are examining whether school policies were violated.

Fellow athlete Bernard Flynt saw what happened. He was also trying out for the track team Thursday evening. He said Milandu stopped a few feet short of the finish line on his fourth lap.

"He just said he was tired and he couldn't go no more. We was trying to help him, but he wasn't trying to stand up," said Flynt. "He was just trying to just sit there."

Flynt said the weather was rainy and the workout was not particularly strenuous. "He was talking, he was conscious," said Flynt. But then some ten minutes later, Flynt said everything changed: Milandu was lying on a stretcher, then emergency responders were trying to revive him.

Flynt and others simply knelt down and prayed.
