'He's Not Crazy'

Get this man a kidney transplant and book deal, pronto.

The construction worker who was hunting for Osama Bin Laden when he was caught in Pakistan has one thing in common with his prey - bad kidneys.

Gary Brooks Faulkner "is dying," his sister, Deanna Faulkner said Tuesday.

"He only has 9% kidney function, and the only thing that can cure him is a transplant," she told the Daily News. "He needs dialysis three times a week. I'm guessing that he wanted to do one last thing for his country before he died."

Faulkner, 50, was born in California but last lived in Greeley, Colo.

"My brother is extremely religious since his troubled youth," his 47-year-old sister said. "He's not crazy."

Intelligence officials have long suspected that Bin Laden, the monster behind the 9/11 attacks, has kidney troubles and relies on dialysis.

Armed with a sword and pistol and some Christians texts, Faulkner - a construction worker and experienced hunter - was stopped by suspicious Pakistani authorities before he could complete his quest.

"We initially laughed when he told us he wanted to kill Osama bin Laden," said one official, Mumtaz Ahmad Khan, according to The Associated Press.

Faulkner was detained as he trudged through Pakistan toward the border into Nuristan province in Afghanistan, Khan said.

He reportedly told police he had been hunting Bin Laden since the September 11, 2001, terror attacks and intended to lop off his head with the 40-inch sword.

It's been awhile and many believe bin Laden is already dead, but as audacious as Faulkner's mission seemed, there is a big payday involved.

Police said it was Faulkner’s third visit to the area in three years. If the allegations are proven true, it would be the first instance of a bounty-hunter being detained in pursuit of the $50 miliion reward offered by US authorities.
