A 16-year-old boy has been charged with the murders of his mother and three siblings in what's believed to be Utah's biggest mass shooting in 13 years. Authorities say Colin Jeffery "CJ" Haynie sought to kill everyone in his Grantsville home except himself and nearly succeeded Friday. Consuelo Alejandra Haynie, 52, and her daughter Milan (12 or 14; also reported as Maylan) were fatally shot around 1pm, per USA Today. Alexis, 15, and Matthew, 14, were killed after arriving home separately later in the afternoon. Father Colin Haynie was shot in the leg after arriving around 6pm but was then able to wrestle a handgun from his son, police say. Coverage:
