BOARDMAN, Ohio – A 6-month investigation into an 18-year-old in Mahoning County has resulted in his arrest on charges of threatening to assault a federal law enforcement officer.
The investigation started in February, when agents found comments online from a user who discussed supporting mass shootings.
According to court documents, the user posted a threat to assault federal law enforcement officers writing, “…shoot every agent on sight,” in a discussion about the Branch Davidian standoff in Waco in 1993.
Agents met with Justin Olsen, 18, who gave written consent for a search of his car and bedroom, according to a probable cause warrant.
On August 7, agents report they found 10,000 rounds of ammunition, camouflage clothing, camouflaged backpacks, 15 rifles and shotguns and 10 semi-automatic pistols.
Olsen faces one charge for the threat posted online.
