On Sunday, Oct. 1, Stephen Paddock opened fire on the Route 91 Harvest Festival killing dozens and wounding hundreds. Paddock spent hours in casinos. and was known for betting big on video poker and staring down fellow gamblers. There is no indication, though, that any particular grievance set him off.
