On May 12, 1993, Liang, who operated an illegal lottery, had an argument with the shop's owner about the payment of NT$700,000 in gambling debt. When the shop's owner refused to pay, Liang doused himself with gasoline and, shouting curses, set himself on fire in the basement of the establishment, which occupied three levels of a 12-storey building on Songjiang Road (松江路). The blaze quickly spread to the two other levels of the shop, asphyxiating most of the victims. The parlor had been repeatedly warned by police in the preceding months that it was violating safety regulations.
