The Alabama Department of Corrections (ADOC) today announced three arrests related to a crackdown on prison contraband.

According to the department, two people were arrested Wednesday at the Limestone Correctional Facility.

Alabama State Bureau of Investigation agents spotted a suspicious vehicle in the vicinity of state property at the prison and conducted a traffic stop. The ADOC Law Enforcement Services Division K-9 unit searched the vehicle and found a gun and six packages wrapped in black tape, according to an ADOC statement.

Melvin Hayes and MJ Enskat were taken into custody and transported to the Limestone County Jail. They were charged with second degree marijuana possession and certain persons forbidden to possess a pistol.

It’s the second such incident at the prison in a week. A man last week was charged with trespassing and promoting prison contraband after the discovery of 17 suspicious packages on state property.

In an unrelated case, former ADOC Correctional Security Guard Laquetta Harris was arrested on Tuesday, and charged with use of position for personal gain.

She had resigned her position with the ADOC and turned herself in to the Montgomery County Jail.

Further charges may follow in both investigations, the ADOC said.
