A U.S. Army veteran is believed to have killed his wife and two young children before setting their Kentucky home ablaze and taking his own life, authorities said. The man, identified by family as Brad Hettinger, shot and killed his 32-year-old wife, Billie, and their 5-year-old son Colin and 4-year-old daughter Courtney in their home, police said. "It's always difficult, anytime children are involved, it's always difficult," Lt. Todd Kessinger with the Louisville Metro Police Department said. #InsideEdition
