A former letter carrier working with the U.S. Postal Service in Maryland has been sentenced to a year in jail after she was found guilty of delivering packets of marijuana. Washington’s Devona Charley, 27, used to earn $350 a package, The Associated Press (AP) reported.

She was also found guilty of accepting bribes. After spending the designated time in prison, Charley would be kept under house arrest for six months, until her supervised date of release. According to police officials, Charley delivered between 40 kilograms (88 pounds) and 60 kilograms (132 pounds) of marijuana. The cost of the drug she delivered has been valued between $70,000 and $120,000, NBC News Washington reported, citing police officials.

According to her plea agreement, between September 2013 and April 2014, she conspired with 29-year-old Dominique Jones and provided him the addresses on her postal route where he later sent the marijuana. Charley would hand over the marijuana packages to Jones at a predetermined location, even though the parcels were addressed to other people, according to The Associated Press (AP). 

Officials reportedly said that Charley knew the packages contained marijuana.

Jones, who pleaded guilty to the conspiracy, was reportedly sentenced to more than four years in prison, according to NBC News Washington, which added that government officials are now investigating more such cases.
