BOARDMAN – Following a six month investigation FBI Agents say they found 25 guns and 10,000 rounds of ammunition in the bedroom of a Mahoning Valley man. The investigation was launched in February after agents received word of the alarming comments made online by 18 year old Justin Olsen of Boardman.

Court documents show Olsen made comments supporting mass shootings and posted a threat to assault federal law enforcement officers. After receiving written consent from Olsen, agents conducted a search where they found 10,000 rounds of ammo, camouflage clothing and 25 guns that ranged from rifles, shotguns and semi-automatic pistols.

Fox 8 first reported the findings. Olsen currently faces just one charge for the threat he posted online.
