A man accused of robbery and assault was shot and killed in a Salt Lake City court after he lunged at a witness giving evidence.
Siale Angilau, 25, died in hospital after being shot several times by a US marshal in front of the jury at the new federal courthouse.
The FBI said he had rushed towards the witness with a pen in an "aggressive, threatening manner".
Perry Cardwell, who was in the courtroom with his adult daughter, said that the incident was over very quickly.
