US boy, 4, shoots friend in head A four-year-old boy in New Jersey shot and wounded a six-year-old friend in the head, the second such accident involving children in a day in the US. Police in the town of Toms River were quoted by ABC television as saying that the boy was holding a .22 calibre rifle when he shot his friend at a distance of about 14 metres. It was unclear why the weapon discharged. The victim was in hospital in critical condition, the report said. Meanwhile in Tennessee, another four-year-old pulled the trigger of a loaded handgun and killed the wife of the local sheriff's deputy, the owner of the gun. "Split second, we're talking about seconds for that kid to walk in that room unbeknownst to them, grab that gun and it goes off," said Wilson County Sheriff Robert Bryan, speaking on local television. "It looks to be a tragic accident," he also told USA Today. He did not normally have small kids at his house, and his guns were locked prior to coming out.
