Fraud accusations leveled at its former president have led a central Wisconsin veterans group to disband.  A watchdog group says Ronald Worthey lied about serving in Vietnam.  He apparently didn’t earn a Silver Star and three Purple Hearts.  His military records show he served stateside.  Worthey headed the Wausau-based group Souls of Honor.  The group’s vice president says he is forming a new group with a similar mission — to support Wisconsin veterans.  The group Guardians of the Green Beret accused Worthey of fraud.
