An Oklahoma inmate got caught shooting his mouth off over the gun he smuggled into jail via his rectum, forcing him into both a hospital stay and an extended stay behind bars.


KFOR-TV reported that authorities at the Oklahoma County jail were tipped off after Mark Gregory Valadez bragged to other prisoners about smuggling a Derringer pistol into the facility, a practice reportedly known as "keistering."

Valadez managed to avoid going through a metal detector while being booked on Sunday morning on lesser charges, and Sheriff John Whetsel told KFOR a pat-down would not be able to detect it. The weapon reportedly contained one bullet in its chamber when it was discovered.

The suspect's charges were upgraded to a felony count of possession of contraband in a penal institution. The Smoking Gun reported he is being held on $5,000 bond, and also had to be hospitalized.
