Two men were killed Tuesday when the driver lost control of his pickup truck and crashed in Greenville.Police say Adam Janitz, 22, and 18-year-old Richard Cudey were driving on a mountain road when the truck spun out of control, wrapped around a tree and burst into flames. Their bodies were so badly burned it was almost impossible to identify the men. Blood samples were taken to a police laboratory to see if alcohol played a role in the accident.Investigators say they suspect excessive speed may have contributed to the crash.
