A Ransomville woman involved in a marijuana-smuggling operation has pleaded guilty to federal drug-conspiracy charges before U.S. District Judge Richard J. Arcara, U.S. Attorney William J. Hochul Jr. reported Thursday.

Prosecutors said Bonnie R. Gordon, 33, was part of a group that brought marijuana from Canada to the U.S., often hidden in the spare tire of a car. The marijuana was driven to several locations in Niagara County for distribution, investigators determined. Authorities said Gordon admitted that the operation began in 2002 and continued for more than seven years.

Gordon was arrested with five other suspects in December 2011. She is the first to be convicted. She faces a mandatory minimum of five years in prison when she returns for sentencing July 1.
