Bruce Jenner is mourning the school shootings in Newtown, Conn., a little differently than most. He went to high school there, and his sister attended kindergarten at Sandy Hook, the elementary school at which a gunman killed 20 children and six adults last week.

"Not in a million years would you ever think that this quiet little town would have such a terrible, terrible tragedy happen there," the Olympic gold medalist and graduate of Newtown High School told E! News. "You just can't believe it."

Jenner, after whom Newtown High School's stadium was named for 24 years (until the school changed it after not hearing back from Jenner during a fundraising drive), says he first heard about the shooting on TV, and it took him a moment to realize that it was Sandy Hook the newscasters were talking about.

He's been in touch with his sister and his mom, and they were both as shocked and saddened as he was by the tragedy that unfolded.

"I just get mad inside at humanity sometimes and how a twisted mind can be so evil," said Jenner.
