Federal Agents Arrest Former Ohio National Guard Member for Making and Selling ‘Ghost Guns’

COLUMBUS, Ohio – Federal agents arrested a former member of the Ohio National Guard this morning on charges related to making and selling “ghost guns,” untraceable homemade weapons made in whole or in part with a 3D printer.

Thomas Develin, 24, of Columbus, also allegedly made antisemitic and violent statements while employed to provide security services at local synagogues and Jewish schools.

It is alleged that Develin created ghost guns to sell for profit. It also alleged that Develin possessed homemade conversion devices to convert semi-automatic AR-15 rifles and Glock-type pistols into fully automatic machine guns.

Agents discovered more than 25 firearms in Develin’s residence and vehicle while executing a search warrant in March 2022.

According to an affidavit filed in support of the criminal complaint, Develin’s Discord and Snapchat activity online revealed a large quantity of antisemitic, white nationalist, racist and misogynistic content. Develin used the fictional name “Patrick Bateman” online.

For example:

  • In September 2021, it is alleged Develin posted a picture of the synagogue where he was working at the time and stated, in part, “Having an inner debate that if an active shooter comes in I might just join him.”
  • In November 2021, Develin allegedly posted a video of himself sniffing a rifle. In the video, Develin says, “This one smells like dead Jews.”
  • In a December 2021 Discord post, Develin allegedly wrote, “Ight, time to turn wright pat airbase into Fort hood in 2009.”
  • In January 2022, Develin allegedly posted a picture of a New Albany synagogue with the text, “The holocaust didn’t happen” and “If anything I’ll scream 6 million wasn’t enough.”
  • A Snapchat video in March 2022 shows Develin displaying a firearm at a Jewish school in Columbus.
  • Develin also allegedly posted multiple times advocating the rape of women.
  • Additional messages Develin posted online discussed committing terrorist attacks at John Glenn International Airport and at the Budweiser manufacturing facility in Columbus, and killing a Morgan County Sheriff’s deputy and the deputy’s entire family.

The defendant has been charged in the Franklin County Court of Common Pleas with various crimes, including making terroristic threats. Those charges remain pending.

Develin will appear in U.S. District Court this afternoon regarding his federal charges.

Kenneth L. Parker, United States Attorney for the Southern District of Ohio; Daryl S. McCormick, Special Agent in Charge, U.S. Bureau of Alcohol, Tobacco, Firearms & Explosives (ATF); and Columbus Police Chief Elaine Bryant announced the charges. The agencies were assisted by the Federal Bureau of Investigation (FBI). Assistant United States Attorneys Peter K. Glenn-Applegate and Jessica W. Knight are representing the United States in this case.

A criminal complaint merely contains allegations, and defendants are presumed innocent unless proven guilty in a court of law.
