(AP Photo/Fort Worth Police Handout) (Newser) – A 14-year-old North Texas boy has pleaded guilty to fatally beating a 5-year-old with a bowling ball after becoming irritated when the child kept asking to be taken to the store. Sida Osman was found dead in the backyard of a vacant Fort Worth home in June, a day after he was reported missing while riding his bike. Authorities say the teen had told others that he struck the 5-year-old twice in the head with the ball when the boy kept pestering him. The Fort Worth Star-Telegram reports that the teen pleaded guilty today to capital murder and will be incarcerated for 23 years as part of a last-minute plea agreement. Authorities are not identifying the Fort Worth teen because he's a juvenile.
