The kid has confessed that he is a sex addict, he frequented these three brothelsparlors spas, and he shot the women to attempt to stop his opportunity to act on his addiction. There have been interviews with friends, classmates, and others who state they never knew him to make any racist comments. However, the women were Asian, he is white, and they found a T-Shirt referring to the china flu in his stuff.
I'm sure the local cops would love to state that this is better described as local John shot up three brothels and shot seven prostitutes and a John. However, we gotta push race, prejudice and hate all we can.
