Two metro Atlanta residents involved in a scheme to deliver methamphetamine to inmates at two Georgia prisons pleaded guilty to federal drug charges, the Department of Justice announced Wednesday.

Crystal Avery, 37, of Lithia Springs, and Timothy Bailey, 31, of Lawrenceville, were arrested last May when the pickup truck they were in got stuck in a field behind Calhoun State Prison, authorities said.

The two were there dropping off bags containing 57 grams of meth to be collected by the prison work detail and were working with 35-year-old inmate Cody Brousshard to deliver the contraband, the DOJ said in a news release.

Bailey admitted to delivering bundles of drugs to Georgia prisons at the direction of Brousshard on four occasions: twice to Calhoun State Prison in Morgan and twice to Dooly State Prison in Unadilla, where Brousshard was previously housed, federal prosecutors said.

Avery pleaded guilty Monday to one count of possession with the intent to distribute controlled substances. Bailey pleaded guilty to the same charge Tuesday.

Brousshard, who is from Lawrenceville, pleaded guilty in December to one count of conspiracy to possess with intent to distribute controlled substances.

"Smuggling illegal drugs and other paraphernalia into our prisons is a serious and ongoing problem that puts our prison employees and other inmates in danger,” said Charlie Peeler, U.S. Attorney for the Middle District of Georgia. “We are targeting these inside jobs, and we will ferret out those inmates attempting to continue their criminal ways while incarcerated, and those on the outside who choose to engage in this unlawful conduct.”

The charges carry a minimum sentence of 10 years and a maximum sentence of life in prison as well as a $10,000 fine, authorities said.

Sentencing dates for Brousshard, Avery and Bailey have not been finalized.
