PHILADELPHIA — (CNN) A man who once climbed a wall near the White House was shot and killed at a Pennsylvania courthouse Tuesday after slashing a deputy sheriff with a knife, an official told CNN affiliate WPVI-TV.

Curtis Smith entered the lobby of the Chester County Justice Center in West Chester and attacked the deputy sheriff, according to a statement from Chester County District Attorney Thomas Hogan. Another deputy sheriff drew his weapon and shot Smith.

The injured deputy sheriff was transported to an area hospital, where he was in stable condition. Smith was also transported to the hospital, where he was pronounced dead.

Although he did not say in his statement, Hogan told WPVI that Smith is the same man who climbed an outer stone wall near the White House in March.
