Curtis Smith, better known as the man who jumped the fence guarding the White House in March, was killed Tuesday inside a Pennsylvania courthouse. Smith was shot dead after slashing a sheriff's deputy with a knife, according to MSN.

Smith, 34, was killed by a second deputy around 11 a.m.. He was in the lobby of the Chester County Justice Center, near Philadelphia, at the time. Kevin Brough, the attacked deputy, suffered a cut to his left arm and hand. He was scheduled for surgery Tuesday night.

It's not known why Smith was at the courthouse. He was previously arrested on March 1 of this year after climbing and jumping a wall surrounding the White House in Washington, D.C. At the time, he said he wanted to "pass a message" to President Barack Obama. He offered no resistance during his arrest at that time, MSN reported.

A lawyer who represented Smith in a domestic violence case told reporters that Smith was a truck driver by trade. Smith "had a family, a wife," attorney Lewis Hannah III said, according to The Inquistr.

Smith was pronounced dead at a local hospital shortly after being shot. The courthouse was locked down and closed after the shooting.

The deputy who received the knife wounds was the only person injured, other than Smith, and remains in stable condition at the hospital, according to Yahoo! News. Smith was charged with unlawful entry for his antics at the White House, and was ordered to stay away from the official presidential residence for six months. The case was agreed to be dismissed, so long as Smith followed that mandate and broke no other laws during his White House probationary period. His follow-up hearing was scheduled for Oct. 9 of this year.
