In the early hours of Christmas Day, Anthony Quinn Warner parked a motorhome in front of the AT&T network center on Second Avenue in Nashville, Tennessee.
Several hours later, at around 5 a.m., several loud bangs, recognized by locals as gunshots, were heard. Some 5 to 15 minutes later, there were more gunshots, prompting people to call 911. Around 5:30 a.m., a recorded message began blasting from the recreational vehicle, warning that vehicle was going to explode.
