Curtis Smith, 34, of Coatesville was killed by another deputy after the attack about 11 am in the lobby of the Chester County Justice Center in West Chester, Pa, District Attorney Thomas Hogan said at a news conference, the USA Today reported citing local media.
Deputy Kevin Brough, who has been on the force for 18 months, was cut on his left hand and arm. He was slated for surgery Tuesday night at the Hospital of the University of Pennsylvania, said Sheriff Carolyn Bunny Welsh, the Philadelphia Inquirer reported.
Smith was pronounced dead at Paoli Hospital. Officials did not immediately say how many times he had been shot. It was not clear why he was at the courthouse or what prompted the attack.
A lawyer representing Smith in a pending domestic-violence case told WCAU-TV his client "had no terrorist claim or anything like that."
The courthouse was locked down for about two hours and then closed the rest of the day. Trials and court business for those inside continued, however, the Delaware County Daily Times reported.
“Unfortunately, because of incidents like this across the nation, we have learned how to deal with an attack at a courthouse,” Hogan said. “No one else was injured. The sheriffs did their job, and the lockdown went perfectly."
Smith was arrested March 1 after he scaled a stone wall at the southeast corner of the White House complex. The arrest record said he wanted "to pass a message to the president," the Washington Post reported. He offered no resistance and "turned around presenting his hands behind his back for arrest."
