Samuel Borntreger, 39, was Jan. 10 in Harrison County with a first-degree murder.
According to court documents Borntreger allegedly admitted to deputies in Kentucky to killing his then wife Anna Borntreger by giving her battery acid up her rectum twice in one day and antifreeze in her drinks sometime between Nov. and Dec. of 2006.
Borntreger allegedly went to Kentucky authorities in January and told them about the case. No foul play was suspected when she died.
In court hearings, Borntreger’s attorney has said he and his client are in plea negotiations with prosecutors.
