FBI: Procedure change contributed to shooting in Utah court

SALT LAKE CITY (AP) — An FBI report about a shooting inside a new Utah federal courthouse found a lack of communication and a procedural change contributed to the death of a prisoner.

The Salt Lake Tribune reported Sunday that 25-year-old Siale Angilau was killed by a U.S. marshal when he lunged toward a witness during his April 2014 trial in Salt Lake City.

The FBI report says some marshals in the courtroom were unaware of a judge’s decision to leave Angilau unshackled due to a lack of table drapes in the new courtroom.

Officials say drapes are frequently used to hide restraints from juries to prevent prejudicing their opinions of defendants.

The U.S. Department of Justice announced the marshal was justified in shooting Angilau four times and that no charges would be filed.
