A 13-year-old Iowa teenager died last Saturday, ten days after sustaining fatal injuries in a tragic sledding accident. The Gazette reported that 13-year-old Adam McWherter died as a result of the injuries he suffered after the boy’s sled accidentally slid into the road and he was hit by a 2008 GMC Envoy on Jan. 10. At the time of the accident, McWherter was sledding down his driveway with his 11-year-old friend.
