He started playing the game when he was four years old and practically played year-round because he just couldn't get enough of the game.
"He was really driven. He was a really big competitor," said Mark. "When I would watch him on the bench, he was never goofing around, was always watching game play talking to his linemates pointing out what was going on."
As is typical for youth players, Henry usually wore a neck guard. But on the day of the accident, he had lost his and thus wasn't wearing it when he took the ice at Capital Clubhouse.
During the clinic on August 18, he was skating around and behind the net while other players were taking slapshots towards the net.
One of those slapshots struck Henry in the neck causing a catastrophic brain injury and a severed artery. Henry was rushed to a D.C. hospital, where he tragically died with his parents at his side.
