GRAND RAPIDS, Mich. (WOOD) — A Grand Rapids man monitored for months by the FBI after allegedly building bombs also stockpiled parts for an AR-15, a federal indictment indicates.
A Grand Jury indicted Aaron William Fein Tuesday on two charges of lying to an FBI officer.
The indictment says on May 3, Fein lied to the FBI about having guns or components for guns at his home. Authorities say they found two lower-receivers, a pistol grip and a lower-receiver parts kit for an AR-15 at the home.
Fein, 24, first showed up on the FBI’s radar in August, when he was stopped at the U.S.-Canada border with a notebook containing a handwritten checklist of ingredients to build a bomb that could be remotely detonated, a federal criminal complaint shows.
The criminal complaint says Fein alerted federal authorities to “partially-constructed electronic triggering devices” in his bedroom he said he built.
In interviews with authorities, Fein sympathized with mass shooters and admitted to posting pictures of them, saying he was unemployed and that maybe he should “go shoot up a school.”
The criminal complaint also outlined Fein’s mental health struggles and repeated attempts to buy a gun, despite a court order to not own a weapon. Fein visited three stores in the Grand Rapids area, but was flagged in background checks and refused a gun.
The indictment states when Fein was stopped near the Michigan-Ohio border last month after visiting other gun stores and ranges, he denied handling or firing a weapon during his travel. However, investigators had determined Fein used an AR-15 at an Ann Arbor gun range on April 18.
Each federal charge of making a false statement carries a punishment of up to 5 years in prison, three months’ probation and a $250,000 fine.
Fein is expected back in Grand Rapids’ federal court on May 21.
