Oregon National Guardsman Alek Skarlatos, one of three Americans who tackled and disarmed a gunman on a France train, was a former student at Umpqua Community College, where today's deadly campus shooting took place.

Tonight, Skarlatos went "On The Record" with Greta Van Susteren to discuss the tragic shooting.

He revealed that he was already enrolled for fall classes at the college before the train incident, which caused him to pull out of school.

Skarlatos said Roseburg, Ore., is a very small community where everybody knows each other, so the chances are that he will know some of the victims.

"It's the only college around, so everybody goes there," Skarlatos said. "It's tragic, it's horrible for the community."
