A judge in Centerville has cancelled a plea deal for a Centerville woman who pleaded guilty in the death of her infant son.  In August, 31-year-old Brittney Keller pleaded guilty to child endangerment and drug charges.  Keller acknowledged that in May of this year, she left the bathtub running with her 11-month-old son and his sister in the tub.  Her son was taken to the hospital, where he died.  A plea deal was set up where Keller would get a suspended jail sentence and be ordered to have mental health and drug treatment.  But on Wednesday (12/4), Judge Rose Anne Mefford sentenced Keller to two years on each count.  The sentences will run concurrently and Keller will get credit for time served.  Keller was originally charged with child endangerment causing death.
