The 25-year-old Virginia man convicted of shooting an unarmed security guard at the offices of the right-wing Family Research Council headquarters in Washington, D.C., was sentenced on Sept. 19 to 25 years in prison.
Floyd Lee Corkins II has said he wanted to kill as many as possible at conservative organizations such as the FRC, which promote discrimination against LGBT people.
Corkins, according to federal authorities, had once volunteered at an LGBT community center in the D.C. area.
He was arrested at the FRC office building in August 2012 after he was tackled to the ground by the security guard he shot and wounded.
Corkins was in possession of a gun and also 15 day-old of Chick-fil-A sandwiches, which he apparently planned to smash in victims' faces.
The judge on the case, U.S. District Court Chief Judge Richard W. Roberts, called Corkins' crime horrific, according to the Washington Post.
The Post quoted the judge as saying, "The carnage you wanted did not happen only because an ordinary man showing extraordinary courage stopped you. Killing human beings is not political activism. It is criminal behavior.”
Corkins had pleaded guilty in February to three felony charges: transporting a firearm or ammunition across state lines, assault with intent to kill and committing an act of terrorism while armed. The first was a federal charge and the second and third were D.C. charges.
Six months before the shooting, Corkins was committed to a mental hospital because he was hallucinating and thinking about killing his parents and right-wing Christians, according to the Post report.
He purchased the 9mm SIG Sauer pistol he used in the shooting from a Virginia gun shop six days before the incident.
