Charlotte police are dealing with another grim killing involving children. They say a man killed his young son and daughter, then set their house on fire. Gilberto Miranda Cuellar is hospitalized with unspecified injuries. Police say he was arrested after someone called authorities to where he was found a couple of miles from the home. The bodies of his five year old son and eight year old daughter were found by firefighters. Both had been shot. It's the third time in two months that a parent in the Charlotte area has been accused of killing their children. A banking executive and a Midland woman are each charged with murder in separate cases, in which authorities say each killed their two kids.
