COURTHOUSE SHOOTING

Law enforcement officers fatally shot a criminal defendant standing trial in Utah’s new federal courthouse on April 21 after he allegedly tried to attack a cooperating witness. Siale Angilau “rushed a witness on the witness stand in an aggressive, threatening manner,” the FBI said. He was shot in the chest and died after being ­transported to a local hospital. Angilau faced racketeering charges in connection with his alleged involvement with the Tongan Crips Gang, a group prosecutors claimed was responsible for a series of ­violent crimes.
