BOSTON >> Federal prosecutors say a former airline employee is headed to prison for his role in a scheme to smuggle what he believed was drug money through Boston's Logan International Airport.

Twenty-nine-year-old Dino Dunkley of Mattapan was sentenced Tuesday in Boston to two years in prison. He pleaded guilty in December to conspiracy to defraud the U.S. and illegally entering an airport area with intent to commit a felony.

Federal agents launched an undercover sting operation in 2012 after discovering security lapses and the potential for airline workers to smuggle contraband around the employee security system.

Authorities say the former Delta Airlines worker twice used his security credentials in 2012 to evade checkpoints and smuggle a combined $100,000 through the airport. Court records show the cash was planted by undercover agents.
