Turns out that it was a Taiwanese Church. Shooter apparently was of Chinese origin and the reports I heard said he had China-Taiwan beef, so basically hate crime against Taiwanese people.
Would have killed more people but one of the churchgoers rushed and tackled him, stopping the attack, and others were able to pile on and hogtie him before the cops got there. The guy who rushed him got shot in the process and passed away. Five other people shot, 4 of whom are in critical condition.
Damn Dat asian on Asian crime... but-but but stop Asian hate tho right???
