Investigations continue into the death of a teenage snowboarder.  

Wyatt Colvard, 18, of Fountain Valley was found unconscious lying in the snow Tuesday morning at the Heavenly Ski Resort and later died of his injuries.  

Apparently, nobody saw what happened to the victim, but authorities say he died of internal injuries due to blunt force trauma.  

He was on an expert snowboarder run. Authorities are speculating that he lost control and crashed into a tree.
