The four men were charged for two distinct sets of conduct involving Vlamis. In December, Bin "Chen" Luo and Bao Xion Zheng allegedly purchased 62 cases of liquor from Vlamis, paying $9,386 in cash, and then took them back to New York, where Zheng owns Bao Liquors in Flushing, Queens. The Homeland Security Investigations task-force officer who swore out the charges against them, Baltimore Police Det. Robert Gerace, wrote in his complaint that he has "previously observed" the two men "purchasing bulk quantities of liquor at Vlamis Liquors" and "unloading cases of liquor into Bao Liquors." The other two men, Ke "K" Yao and Yi Feng "Steve" Gao, earlier this month allegedly paid Vlamis $9,618 in cash for 35 cases of liquor, which they loaded into a 2007 Hummer H2, "concealed the load with blankets and sheets, and returned to New York." Gerace also had previously seen Yao and Gao making bulk purchase of liquors at Vlamis and "moving cases of liquor into retail liquor stores in New York."
