ARLINGTON, Wash. – An Arlington man found with an arsenal of weapons and an explosives lab is headed to prison for three and a half years.

The U.S. Attorney in Seattle says 42-year-old James Wesley Bowden pleaded guilty to multiple charges.

Officers arrested him in November 2021 after he threatened another man with a gun.

They found an explosives lab in Bowden’s garage along with a passageway that led to an underground bunker.

There they found guns, grenades, silencers, body armor and more.

Two of the firearms had been modified to be fully automatic.

Bowden is a convicted felon who is barred from possessing guns.
