EAST ST. LOUIS — A 40-year-old Centralia woman has been sentenced to more than 4 years in prison after she earlier pleaded guilty in federal court to methamphetamine related charges.

Dusty Jo Gambill has been sentenced to 57 months in federal prison, fined $400, and ordered to pay a $200 special assessment. Upon her release from federal prison she will have to serve 3-years supervised release.

Gambill pleaded guilty in July to a charge of Conspiracy to Manufacture and Distribute Methamphetamine which operated from February 28th, 2014 through October 1st, 2014 in Clinton and Marion Counties and for possession of a listed chemical (Pseudoephedrine) knowing it would be used to manufacture methamphetamine.

The charges were brought by a Federal Grand Jury in December 2014. Gambill has been in custody since July 21st, 2015, when her bond was revoked.

Four others charged in the conspiracy, Michael Alan Flanagan, James Perry Horton, David Leroy Altom, and Kathy Sue Tomes have all pleaded guilty and are awaiting sentencing. Another co-conspirator, Jayme Lee Barnes, was sentenced in September to five years in prison, four years’ supervised release, a $200 fine and a $200 special assessment.

Information leading to the charges against Gambill and the others was obtained in an investigation conducted by the FBI, the Marion County Sheriff’s Office and Clinton County Sheriff’s Department, assisted by the Illinois State Police Methamphetamine Response Team, and the Centralia Police Department.

The case is being handled by Assistant U.S. Attorney Kit Morrissey.
