After nearly a decade a Kentucky man had confessed to killing his wife when they lived in northwest Missouri.

Samuel H. Borntreger, 39 was charged Sunday in Harrison County with a felony for first-degree murder stemming from an incident that took place in 2006.

“I got a phone call Sunday from a deputy advising that he had got a phone call from a sheriff’s office in Kentucky about an Amish man coming in and confessing to murdering his wife back in 2006 here in Harrison County,”said Sheriff Josh Eckerson with the Harrison County Sheriff’s Office.

According to court documents Samuel Borntreger admitted to deputies in Ken. to killing his then wife Anna Borntreger sometimes between Nov. and Dec. of 2006.

“Samuel admitted to giving antifreeze in her drinks,”said Sheriff Eckerson. “Samuel admitted to giving Anna battery acid up her rectum twice in one day.  Samuel admitted to giving Anna the antifreeze and acid to kill her.”

Anna’s body was exhumed Tuesday from an Amish cemetery in northwest Missouri.

“She was taken down to Kansas City to a medical examiners office where they will run some tests and let us know in fact have any signs of any of that in any of her system.  Hair, bone-marrow, any of her tissue,” Eckerson said.

Eckerson said Borntreger recently became a minister.

“He came forward because he said he wanted to get it off his chest, it was weighing heavy on his mind,” Eckerson said.

Prior to moving to Kentucky Borntreger was part of the Amish community in northwest Missouri and was a well-known cabinet maker.

Borntreger is scheduled for an arraignment in Harrison County for Jan. 20.
