NEW ORLEANS (AP) — The FBI has joined New Orleans police to request the public's help in the search for a suspect in the 2013 death of an armored car guard.

Twenty-four-year-old Robert E. Brumfield III of New Orleans is one of five people facing federal charges in the death of guard Hector Trochez.

Trochez was shot to death at a bank In New Orleans' Carrrollton area as he made a cash delivery. Indictments of five men suspected in the death — and a woman charged with obstruction — were unsealed Monday.

Brumfield is the only one who remains at large. The armored car company, Loomis Armored US, is offering a $5,000 reward for information leading to an arrest.
