The Islamic Center of Fort Pierce, which Orlando gunman Omar Mateen attended, was set on fire early on September 12. While no motive has yet been established, early evidence revealed that the fire was intentional. “Right now, I don’t want to speculate on a motive,” Major David Thompson told media. “We all know the implications of the date and the time of year, that this is the 9/11 anniversary. Is that related? I would not want to speculate, but certainly that it is in the back of our minds.” The attack also occurred on the Muslim holiday of Eid al-Adha.
