A man found with four guns, silencers, methamphetamine and more than 100 rounds of ammunition in an apartment near the Portland State University campus was sentenced Monday to six years and three months in federal prison.

Fredric Russell Dean, 40, pleaded guilty to possessing an unregistered short-barreled rifle, his fifth illegal gun conviction.

His sentence included a two-year prison term for violating his federal supervision from a 2014 conviction as felon in possession of a gun.

Officers with the U.S. Marshals Fugitive Task Force arrested Dean on a warrant on Jan. 22, 2018, after finding him at an apartment complex near the downtown university. He wasn’t the tenant but had been staying in the apartment for about two weeks, a manager told the officers, according to prosecutors.

The officers obtained a search warrant for the apartment, where they discovered three handguns, a .223-caliber short-barreled rifle, 1.9 grams of methamphetamine on a couch, more than 150 rounds of ammunition and several gun silencers, according to prosecutors.

At the time of his arrest, Dean had convictions for being a felon in possession of a gun in 2014, 2009, 2006 and 1998 and for identity theft and first-degree burglary in 2006.

Prosecutors argued that federal supervision wasn’t adequate to keep him away from guns.

Dean’s gun possession is directly tied to his methamphetamine addiction, defense lawyer Tiffany Harris told the court. One of the guns seized had been reported stolen.

“When not using meth, he does not possess weapons,’’ Harris said. She added that Dean hasn’t been involved in any assaultive behavior since he was engaged in a fist fight at age 16.

Harris also said Dean has had a recent, serious bout of cancer that may pose a threat to his health while he serves his sentence. She asked that Dean be sent to the federal medical center at Terminal Island in California.

“Cancer is a very humbling experience. It’s given me a new outlook on life,’’ Dean told U.S. District Judge Michael H. Simon.

When out on supervision, Dean plans to live with relatives at his childhood home in Blue River and participate in the federal re-entry court program in Eugene, his lawyer said.

The judge issued the six year and three month sentence, which was jointly recommended by the prosecutors and defense lawyer. He recommended the Terminal Island prison placement. The judge also ordered Dean to live at least four months in a residential re-entry center before he’s released on supervision, and undergo substance abuse treatment and random drug testing while on supervision after his prison term.
