The Ohio Supreme Court has refused to hear a Warren County man's bid for a fourth trial in the 2008 bathtub drowning of his wife.Ryan Widmer's attorneys contend that police improperly removed the couple's bathtub from their home as evidence. Prosecutors responded that the argument had no legal merit. the 12th District appeals court in January rejected a separate appeal focused on a detective's alleged misconduct and lack of testing of Sarah Widmer's remains for a possible genetic disorder. Widmer continues serving 15 years to life for the 20-11 murder conviction.
