Mounties say they have busted a massive Calgary crime network that was trading in millions of dollars worth of illegal tobacco, drugs and stolen property. The federal RCMP’s integrated money laundering investigative team (IMLIT) charged four people with fraud, money laundering and contraband-related offences. Seven search warrants were executed in connection with the investigation in Calgary and Airdrie, which saw the seizure of: Johnathan Patrick Roach, 42, of Calgary, Brock Anthony MacQuarrie, 41, of Calgary, David Shoa Guan, 52, of Calgary and Jason Douglas Pereira, 44 of Airdrie, are all facing charges in the case. All four were arrested in early September and are expected in the Alberta Court of Justice in Calgary on Oct. 19.
