An Ottumwa man accused of murdering his wife wants his bond reduced.  61-year-old Gregory Showalter appeared in Wapello County Court Monday (8/16) to have his $250,000 bond reduced.  He is accused of first degree murder in the death of 60-year-old Helen Showalter.  Her body was found in the Des Moines River two weeks ago.  Gregory Showalter’s attorney argued that he isn’t a threat to the community.  Prosecutors say a $250,000 bond is appropriate for a first degree murder charge.  The judge has yet to decide on Gregory Showalter’s request.
