HONEFOSS, Norway (AP) -- The chief surgeon at a hospital treating victims of Norway's camp massacre says the killer used special bullets designed to disintegrate inside the body and cause maximum internal damage.
Dr. Colin Poole, head of surgery at Ringriket Hospital in Honefoss northwest of Oslo, says surgeons treating 16 gunshot victims have recovered no full bullets.
He told The Associated Press: "These bullets more or less exploded inside the body. ... These bullets inflicted internal damage that's absolutely horrible."
Ballistics experts say so-called dum-dum bullets also are lighter in weight and can be fired with greater accuracy over varying distances. They commonly are used by air marshals and hunters of small animals.
