A Windham woman will spend 15 years is prison after selling over three pounds of meth to an undercover police officer.

A federal judge sentenced 43-year-old Mandy Lynn Shorey Tuesday after she was convicted of trafficking methamphetamine and for possessing a firearm in furtherance of a drug trafficking crime.

Shorey sold the meth to an undercover officer on four different occasions.

During one of the buys, Shorey told the officer that she carried a firearm when meeting with new drug customers and displayed a gun, which she placed in her waistband.

U.S. attorney Noah Falk said that for three of the buys, the purity of the methamphetamine Shorey sold to police approached 100%.

During another exchange, she told the undercover officer that meeting her to conduct their next transaction would be safe because she would “bring one armed man to back me up that they will never see, just in case. When Shorey was arrested, she was in possession of a Charter Arms .22 revolver.

The FBI Safe Streets Task Force investigated the case.

Shorey was convicted in U.S. District Court in Portland.
