SALT LAKE CITY (AP) — A U.S. marshal shot and critically wounded a defendant on Monday in a new federal courthouse in Salt Lake City after the man rushed at a witness with a pen, authorities said.

Defendant Siale Angilau, 25, was hospitalized with at least one chest wound, FBI spokesman Mark Dressen said. Under standard procedures, Angilau was not restrained in the courtroom, the FBI said.
