A Frankford woman was sentenced Monday to four years in prison for her role in a murder case that drew national attention.

Rebecca Kirk pleaded guilty in August to two felony counts of tampering with evidence.

Kirk admitted to damaging or trying to destroy a rifle, ammunition and clothing at the request of Calvin Duane Petty on April 15th of 2010.

Petty was having an affair with Kirk even as he was engaged to Sandra Fugate of Hannibal. Petty was convicted in June 2012 of murdering Fugate and admitting the crime to Kirk. The homicide happened just two days before Petty and the victim were to be married.

Kirk admitted on the witness stand at Petty’s trial that she followed through on the defendant’s request to destroy evidence. She said she was sorry for her actions.

The case was featured earlier this year on the Investigation Discovery channel show “Happily Never After.”
