New Orleans Prisoner Accused of Escaping From and Killing Cop 'Apparently Double-Jointed'

— -- The prisoner who shot and killed a police officer who was transporting him in New Orleans was "apparently double-jointed," police said as they launched a manhunt for the alleged shooter.

Travis Boys, 33, despite being cuffed, managed to grab a gun, and shoot Officer Daryle Holloway, 45, who later died at a hospital, according to the Associated Press.

New Orleans Police Chief Michael Harrison described Boys as "apparently double jointed," saying that he managed to move his hands from behind him in front, according to an interview with ABC News Affiliate WGNO-TV.

After that, he climbed through an opening in the cage that separates the front and back of the car and allegedly shot Holloway.

The police SUV then crashed into a utility pole and Boys escaped, police said.

Harrison said that Holloway, a 22-year veteran and father of four, put up a fight and tried to keep Boys in the car but “succumbed to his injuries.”

“Our prayers and our condolences are with his family,” Harrison said. “I’ve known him for 22 years. I’ve worked with him in our early years and he was a personal friend of mine. Great police officer.”

It was not clear which gun Boys used, but police said they do not believe it was Holloway's, the AP said.

The gunman, who had been arrested for assault, was still at large as of Saturday evening and a $10,000 reward was being offered for his capture.
