269: Michael Gibeley – Thwarted Anti-Government Murder Plot

Retired agent Michael Gibeley served in the FBI for nearly 24 years.

In this episode, Mike Gibeley reviews his undercover role as a firearms dealer working with Edward McLarnon who was plotting to illegally purchase weapons to carry out an anti-government plot to murder officials in New Hampshire and his ex-wife’s husband.

Boston Division special agent Brian P. LeBlanc was the case agent of the anti-government domestic terrorism investigation.

Mike was an FBI certified undercover agent for more than 20 years and worked many undercover operations across the United States and countries around the world.

His undercover assignments were for varied violations, including anti-government domestic terrorism, international terrorism, organized crime, drugs, white collar crime, crimes against children, national security matters, public corruption and other investigations.

After graduating from the FBI academy, Mike’s first assignment was to the Philadelphia Division, where he worked on a transnational organized crime squad targeting international drug trafficking organizations. He was later transferred to the Boston Division, where he worked undercover while assigned to organized crime and international terrorism squads, before moving to the Portsmouth, New Hampshire Resident Agency office.

During his Bureau career, Mike was awarded the FBI Boston Division’s Paul Cavanaugh Special Agent of the Year Award in 2015, several Department of Justice Awards, and the Organized Crime Drug Enforcement Task Forces (OCDETF) Case of the Year award.

Toward the end of his career, Mike became the Supervisory Senior Resident Agent for the New Hampshire offices of the FBI. His last assignment before retiring was Acting Assistant Special Agent in Charge of Boston’s Counterterrorism branch. Despite being a member of management, Mike worked undercover until the very end of his career and, at his retirement in Sept 2021, was presented with the United States flag that flew over FBI headquarters on the 20th anniversary of 9/11.

Mike is a graduate of the United States Coast Guard Academy, served in the Coast Guard for 9 and a half years, and earned a Master’s Degree in Criminal Justice from Northeastern University.

So, we went outside and shot a bunch of rounds. While we’re shooting, he turns and looks at me and whispers, ‘This would be a great place to kill an FBI agent.’”—Retired Agent Mike Gibeley
