A stake-out by Dallas County Sheriff’s Department criminal investigators at the county jail has resulted in the arrest of a correctional officer.

Jonathan Alexander, 57, of 2954 Landline Road, Selma, was arrested and charged with promoting prison contraband, second-degree, Saturday at 12:25 a.m. He is in the Dallas County Jail under no bond.

Sheriff Harris Huffman said Alexander was hired as a correctional officer at the jail in January 2009. He was fired as a result of the arrest.

“I don’t know when it started,” Huffman said of the contraband coming into the jail. “But I do know when it stopped with this one, anyway.”

Investigators nabbed Alexander as he reported to the jail with several bags filled with contraband, including a 12-pack of beer; numerous packages of Bugler tobacco, rolling papers, cigars, cigarettes and lighters; chips, cookies, peanuts, Kool-Aid and candy bars; deodorant, soap, toothpaste; cell phones and chargers; gin; and home-made sandwiches, grilled chicken and sandwiches from local fast-food restaurants.

Investigators also recovered a bag of green, leafy material believed to be marijuana, several small bags with white powder and a plastic bag that contained a white rock substance.

Alexander has not been charged with any drug-related offenses.

“Drug charges are pending test results,” Huffman said.

Investigators also recovered handwritten lists of items sought by prisoners.

The sheriff said Alexander admitted he had brought the items to the jail.

“There were no problems with the arrest,” Huffman said.

Investigators John Hatfield and Mike Grantham worked the case after the sheriff’s department received information from a source about someone smuggling contraband into the jail, the sheriff said.
