A bagel shop, Dunkin' Donuts, Wendy's, Fire Station, 7-11, but no mosque. At least I don't see one on Google Earth. But, if the Twitter photo is right, hardly a question of the perps leanings. He's an Islamic terrorist!
The closest mosque is Masjid Qubaa, 3043 Curry Ford Rd #2, Orlando, FL 32806. There are six mosques in the area. Looks like a significant muslim population in Orlando.
