The head of Thailand immigration police said Thursday that Karr admitted to the killing after he was arrested at his downtown Bangkok apartment Wednesday night. Karr arrived in Bangkok on June 6 from Malaysia to look for a teaching job, Lt. Gen. Suwat Tumrongsiskul told The Associated Press.

"John and Patsy lived their lives knowing they were innocent, trying to raise a son despite the furor around them," Wood said. "The story of this family is a story of courage, and story of an American injustice and tragedy that ultimately people will have to look back on and hopefully learn from."

The attorney said the Ramseys learned about the suspect at least a month before Patsy Ramsey?s death. "It?s been a very long 10 years, and I?m just sorry Patsy isn?t here for me to hug her neck," Wood said.

Child pornography charges

It was widely reported, but not confirmed by authorities, that Karr taught in California until he was stripped of his teaching credentials following an arrest on child pornography charges.

Sonoma County Chief Deputy District Attorney Joan Risse confirmed the child pornography charges and arrest warrant against a John Mark Karr, though she cautioned that she didn?t know if he was the same person held in the Ramsey case. State records show Karr lost his teaching credential in 2002.
