The overdose death in July of a Mobile County Metro Jail inmate may be connected to the arrest of a corrections officer who allegedly smuggled fentanyl into the lockup, according to the county sheriff.

Authorities are looking into the possibility that corrections deputy Jessica Monique Odom brought the fentanyl into the jail that killed inmate Terrell Markuise Moultrie in July, said Mobile County Sheriff Paul Burch, Fox 10 reported.

Odom was arrested Thursday on charges of trafficking fentanyl and attempting to pass contraband and drugs

The corrections deputy allegedly smuggled in sheets of paper laced with fentanyl into the county jail, according to Fox 10.

She pleaded not guilty to the charges Wednesday.

Burch said fentanyl that makes its way into Mobile County Metro Jail is divided up and sold by inmates, who either swallow, smoke the drug or dissolve it into coffee.

“They’ll have a piece of paper, and they’ll tear a corner off,” he said, according to Fox 10. “That’s 40 bucks. And like I said, this piece might be fine; the next piece might be fine. Then you get one down here that’s a little more saturated, it will kill you.”
