With a soaring career, private education and stunning fiancee, Sydney man Bennet Schwartz had everything he could have dreamed of.But it was 'greed' that motivated him to develop a double life as a criminal figure and begin transporting massive shipments of cocaine into Australia, NSW District Court Judge Peter Berman said during his sentencing on Thursday.Schwartz, 29, was charged with allegedly smuggling 23kg of cocaine with a street value of more than $7 million to Australia from the United States in 2016, A Current Affair reported.He was dragged off a plane by Australian Federal Police in front of his then-fiancee Sarah Wakefield, who is not alleged to have known anything about her soon-to-be husband's criminal activity.Once a high-flying executive at mining company Rio Tinto and weeks away from marrying the woman of his dreams, Schwatz's downfall was swift and brutal.Two packages containing 25 kilograms of cocaine were intercepted by Border Force and Australian Federal Police before his arrest.The privately-educated executive was to earn a huge payoff for his role in moving the powder to multiple alleged underworld figures in Sydney.Following his arrest, AFP officers took control of his military-grade encrypted Blackberry and began to act as him while communicating with other alleged crime figures believed to be linked to the drug syndicate.In two separate busts, officers intercepted one parcel from Los Angeles containing 15 kilograms of cocaine, labelled as car parts, and another containing 10 kilograms of the narcotic.During his time in prison, Schwartz has had a target on his back after being falsely labelled as a police informant because he had given officers access to his Blackberry.The Downing Centre District Court heard the Sydney man had been intimidated and brutally attacked during his time behind bars, and stood over as details of his privileged upbringing came to light.Kings Cross identity Elias Dimarelis, who was Schwartz's cellmate for nine months last year told ACA the man had been beaten over the head with a Breville sandwich press, stabbed and had a threat made against his life by another inmate demanding $30,000.Schwartz pleaded guilty to two charges of importing a commercial quantity of cocaine, and was handed down a heavily discounted sentence on Thursday.He will be eligible for parole in March 2020, but will have no fiancée and no executive career to return to.
