GRAND RAPIDS, MI – A “person of interest” in three Grand Rapids bank robberies has been indicted on federal firearms charges after, the FBI says, he posted photos on Facebook as he held firearms.

Hollis Clinton Nunnery, 24, was arraigned Tuesday, Nov. 12, by U.S. Magistrate Judge Joseph Scoville on charges of being a felon in possession of a firearm and ammunition.

Nunnery pleaded not guilty.

Scoville ordered Nunnery’s continued detention pending trial. Nunnery was arrested last month on a criminal complaint alleging he illegally possessed firearms as a felon, records showed.

Grand Rapids police consider Nunnery a person of interest in three Chase bank holdups over the summer, records showed.

An investigator found a Facebook account, not under Nunnery’s name, that contained several photos of Nunnery holding guns, the FBI said.

“The photos showed Nunnery holding a large framed black handgun with what appeared to be a laser sight,” FBI special agent Douglas Brownback wrote in the complaint.

The photos were posted between June 8 and Sept. 30. The robberies occurred between July and September, the FBI said.

Grand Rapids Police recovered three guns from his girlfriend’s home, police said.
