Special Agent Robert Conners, Special Agent Michael Lynch, Special Agent Terry Hereford, and Special Agent Charles Ellington were killed in an aircraft crash while on approach to Cincinnati’s Lunken Airport near Montgomery, Ohio.

The agents were accompanying a bank fraud suspect and his lawyer to Cincinnati during an investigation. When the plane was approximately 11 miles from Lunken Airport its altimeter indicated false readings, leading the pilots to believe they were at a higher altitude. As a result, the plane struck a set of power lines and crashed, killing all aboard.

The plane was being piloted by Special Agent Conners and Special Agent Hereford when it crashed.

Special Agent Conners was a U.S. Air Force veteran and had served with the FBI for four years. He was survived by his wife and four children.
