Gang member shot as he attacked witness in Salt Lake courthouse

Salt Lake City, UT - Authorities have released the video of a US Marshal shooting an accused gang member who tried to attack a witness with a pen at the Salt Lake City Federal Courthouse.

The video from 2014 shows Siale Angilau leaving the defense table, picking up a pen and rushing at a witness who was testifying.

"Deputy Jane Doe" fired four shots at Angilau, killing the man, according to court documents.

United States District Judge John E. Dowdell granted the summary judgment Friday and dismissed the plaintiff's excessive force claims.

Angilau's family argued the use of deadly force was not permissible in this case and claimed that the deputy fired several shots into Angilau's back after he was already incapacitated.

The judge disputed these claims saying the deputy and witness were boxed into a corner with no room to escape the attack and the deputy had reasonable belief that Angilau was going to harm or kill the witness or other innocent bystanders.
