This morning, investigators are looking for a motive into the shooting at the headquarters of the Family Research Council.

The FBI says the suspect is 28-year-old Floyd Lee Corkins. He allegedly shot a security guard, who then wrestled him to the ground. Corkins is in custody and is charged with assault with a deadly weapon. The guard is in stable condition.

The motive is still unclear, but a source working with the DC Center for the LGBT community tells CNN that the suspect had worked as a volunteer at that center.
