The sentencing of a Herndon man who shot a security guard at the Family Research Council in D.C. has been delayed until July, court records show.

Floyd Lee Corkins II was scheduled to be sentenced Monday. However, a judge agreed to postpone the sentencing after defense lawyers requested more time to obtain and review Corkins' mental health records. Corkins will be sentenced July 15 in D.C. federal court.

Court documents show that Corkins shot and wounded security guard Leonardo Johnson at the Chinatown-area headquarters of the Family Research Council, a conservative lobbying organization, on Aug. 15, 2012. Corkins, who was carrying a bag of Chick-fil-A sandwiches to protest the group's opposition to gay marriage, later told authorities he had gone to the council building to kill as many people as possible.

Corkins pleaded guilty in February, and prosecutors are recommending that he be sentenced to 45 years in prison.
