(Eaton, OH)--A former Preble County police lieutenant is back in jail.  Jason Etter was arrested Tuesday for violating a protective order.  Just a week ago, Etter had pleaded guilty to menacing by stalking after threatening to kill someone.  Court documents indicate Etter entered a woman’s apartment and placed a knife under her throat.  Etter will be held without bond until he can be seen by an Eaton Municipal Court judge.
