JonBenet murder suspect 'sought sex-change treatment'

John Mark Karr, the suspect in the killing of six-year-old JonBenet Ramsey, arrived in the US after a 15-hour flight from Thailand on which he sipped champagne, dined on fried king prawns and roast duck, and exchanged what he described as “small talk” with law enforcement escorts.

Karr voluntarily returned to the US late yesterday and was not handcuffed in his business class seat. He was expected to be detained by Los Angeles authorities pending a hearing on extradition to Boulder, Colorado, where authorities have issued an arrest warrant for him.
