CHICAGO: A simple childish spat over a puppy led an 11-year-old boy to shoot and kill his eight-year-old neighbor in the US state of Tennessee, the girl’s grieving mother said. Latasha Dyer said her daughter was playing outside when the boy asked to see her puppy. Little McKayla said “no,” and shortly after was shot in the chest. Jefferson County Sheriff Bud McCoig said the boy has been charged with first-degree murder. A judge ordered him held in a juvenile detention center until the next hearing, which was set for October 28, McCoig told AFP. The boy was inside his home when he shot the girl with his father’s 12-gauge shotgun at about 7:30 pm Saturday, McCoig said. The gun was legally owned.
