Buying a .22-caliber rifle to protect her children was the “stupidest thing” Shavon Carrillo said she ever did. Early Memorial Day morning, Las Vegas police said Carrillo, 31, grabbed the rifle and pointed it at her 11-year-old son, Israel, who was in a sleeping bag. She told him, ”I love you,” and shot him once through the head, according to a Las Vegas police report.
