"Sniper" is one who takes a high adventitious position and is armed with a firearm, with or without scope. Usually a rifle. This guy planned on his position by asking for a room over looking the venue at 34 floors up. He had enough weapons and ammo for his deed. If he arrived on thursday, he had enough time to scope and "range calculate" his target objectives. They can probably find him on surveillace tape throughout his stay. This guy knew the venue was for Country western white crowds. Now the motive. Why did his Filipino gf leave him?
