Authorities aren’t saying how he might have done it, but a Lac du Flambeau man is in custody for allegedly “causing the death” of another man last month.  Richard F. Allen is being held on one-million dollars bond.  No details of how Wayne Valliere Junior died have been released.  Investigators say they have verified the information gathered from witnesses and co-conspirators singling out Allen as the killer.   Five people have been arrested and charges of first-degree intentional homicide could be filed today in Iron County Court.  Valliere was last seen December 22nd and was officially reported missing Christmas Day.  His body was found New Year’s Day.
