WASHINGTON, DC — Although prosecutors have offered a plea agreement to the man accused in the shooting last summer at the Family Research Council (FRC), FBI investigators and Capital Police have not disclosed whether they have a motive in the shooting at the conservative think tank, nor if the alleged shooter, Floyd Lee Corkins II, is gay.

At a hearing last month, Corkins’ public defender declined to immediately accept the deal, which includes Corkins admitting to a charge of Committing an Act of Terrorism, a crime that has never been prosecuted in the 10 years since the law was enacted.

Corkins, 28, was formerly employed as a part-time volunteer for Washington’s LGBT community center.

The Herndon, Virginia man is accused of shooting security guard Leo Johnson shortly after entering the FRC building. Court documents say that Corkins told Johnson, who was wounded in the arm, “I don’t like your politics.”

Corkins pleaded not guilty to the 10-count grand jury indictment. FBI investigators said they found 50 rounds of ammunition and 15 Chick-fil-A sandwiches in Corkins’ backpack, which suggests the man may have had a mass killing in mind at the time of the shooting.

Administrators with the LGBT center told investigators that they knew little about Corkins, who had volunteered at the center for a few months.

Court documents indicate that Corkins’ parents told FBI investigators that he has “strong opinions” regarding those whom “he believes do not treat homosexuals in a fair manner.”

According to the deal from federal prosecutors, Corkins would plead guilty to three counts: interstate transportation of a firearm, assault with intent to kill while armed, and “intent to intimidate and coerce a significant portion of the civilian population of the District of Columbia and the United States.”

A pre-trial status conference is scheduled for Tuesday, January 8 in U.S. District Court.
