(Eaton, OH)--A Preble County man was sentenced to 15 years to life Thursday for killing a woman with a machete last summer.  Kenneth Brabant thought the driver of a motorcycle passing by his house was his daughter’s ex-boyfriend, but it was not.  Brabant swung the machete and killed Leigha Huff, who was riding on the back.   Brabant won’t be eligible for parole until he’s 75 years old.  He was supposed to go on trial next month, but instead entered a plea agreement.
