The man who authorities say shot a security guard at the D.C. offices of the Family Research Council may have had an additional target in mind, the head of another socially conservative group based in Washington said Friday.

Andrea Lafferty, president of the Traditional Values Coalition, said a member of the FBI’s Joint Terrorism Task Force told her police found a note in the pocket of Floyd Lee Corkins Jr., the alleged gunman, listing the block of her group’s Capitol Hill office.

Lafferty’s statement came a day after Tony Perkins, head of the Family Research Council on G Street NW, told reporters, “We may not have been the only one” when asked why he thought the shooter targeted his organization Wednesday morning. Authorities have not elaborated on that. A D.C. police spokeswoman referred questions to the FBI, and a spokeswoman for the District’s field office declined to comment.

Federal authorities have charged Corkins, 28, of Herndon, with assault with intent to kill while armed and interstate transportation of weapons.

A magistrate ordered him held Thursday for psychiatric evaluation and scheduled a detention hearing for this month. His attorney did not respond to interview requests Friday.

Documents filed by prosecutors in the District’s federal court say Corkins walked into the lobby of the Family Research Council, told security guard Leonardo R. Johnson, “I don’t like your politics,” and shot him in the arm during a scuffle. Police said Johnson subdued Corkins.

Court papers say Corkins was armed with a 9mm Sig Sauer handgun and had two magazines of ammunition and an additional 50 rounds in his backpack. Authorities also said he carried 15 sandwiches from Chick-fil-A.

Corkins had volunteered with a D.C. gay and lesbian group and, according to the FBI, harbors “strong opinions” about people who don’t like homosexuals. The head of Chick-fil-A has spoken out against same-sex marriage, views supported by the Family Research Council and Traditional Values Coalition.

Lafferty said the agent told her the note contained only the address of the 100 block of C Street SE, on which her office is located.

Representatives from two other socially conservative groups based in the District or that have offices here said Friday that they had not been contacted by the FBI.
