From Oregon Live:

An FBI agent is suspected of lying about firing twice at Robert “LaVoy” Finicium and may have gotten help from four other FBI agents in covering up afterward, authorities revealed Tuesday.

Investigators gave no details to explain why the one FBI agent, a member of the Hostage Rescue Team, wouldn’t report the two shots. They also didn’t indicate what his four colleagues on the team did to warrant investigation other than saying it was related to conduct after the shooting.
