Joran van der Sloot looks too happy to me

(CNN) -- Authorities in Peru said Tuesday they have begun disciplinary action against jailers who photographed suspected killer Joran van der Sloot posing with two other men held in connection with high-profile killings there.

The photograph, first aired by the Peruvian television network America TV, shows the 22-year-old van der Sloot standing alongside fellow inmates Hugo Trujillo Ospina and William Trickett Smith II. A fourth man in the picture is not identified.

Peru's National Institute of Corrections said Tuesday that disciplinary action was in the works over the photo.

"On August 23, the Office of Internal Affairs of the institution began administrative and disciplinary actions with the goal of establishing responsibility over the acts of official misconduct by employees of the Castro Castro Correctional Institution," the agency announced. "They improperly used photographic equipment that was meant for administrative duties."

I didn't think he'd still be able to crack a smile after being there for two months. I do like the sense of humor displayed by the little rascal next to him. The hand guns cocked to his and his friend's head with a cheeky grin on his face while shacked up in prison awaiting trial for murder is a bold move.
