An Air Force officer formerly assigned to Wright-Patterson Air Force Base and his wife have entered not guilty pleas to criminal charges in connection with allegations of child abuse in their Niceville, Fla., home, according to court records.

Lt. Col. Dennis E. Jack, 42, and his wife, Tiffany J. Jack, 41, entered the pleas Jan. 15 in Okaloosa County, Fla. The couple have a residence in northwest Florida near Eglin Air Force Base.

Dennis Jack was reassigned to Eglin last month for “humanitarian” reasons after he was on leave from his post as commander of the 88th Comptroller Squadron at Wright-Patterson, according to base spokesman Daryl Mayer.

The lieutenant colonel is now deputy of the acquisition cost division at the Air Force Life Cycle Management Center at Eglin, according to Chrissy Cuttita, an Eglin Air Force Base spokeswoman.

Dennis Jack was arrested Dec. 2 in Niceville and charged with four counts of child abuse and three counts of obstructing justice, according to police and court records. He was released after posting a $4,000 bond.

Tiffany Jack was arrested Nov. 16 and charged with two counts of child abuse and one count of aggravated child abuse, records show. She was released on a $5,000 bond.

According to a Niceville Police Department report, the victims reported the female defendant forced the children to wear urine soaked diapers on their heads while standing on their hands.

Police said a photograph showed two victims were forced to do push ups, one with the victim’s hands on a booster seat and the other on a toy car, with their feet on a kitchen counter.

A male “abuse reporter,” whose name was redacted from the report, told Tiffany Jack the punishment was inappropriate, authorities said. The person who reported the abuse returned two hours later one day and found one of the victims in the same position, police said.

Physical examinations of the children found evidence of bruises and scars to support the allegations, Niceville police and the Northwest Florida Daily News have reported.

Robert A. Dees, a Florida attorney representing Dennis Jack, declined comment Wednesday. Coy H. Browning, a Florida lawyer representing Tiffany Jack, also declined comment through an assistant.
