LOUISVILLE, Ky. (WDRB) -- One man pleads guilty to murder and robbery in connection with an incident in 2015 at John's Coin and Jewelry Shop in Austin, Ind.

James Matthew "Matt" Caudill, 22, pleaded guilty on Thursday to murder, robbery and an "enhancement" charge of using a firearm in the crime.

He admitted to the crime as part of his plea agreement, less than a week before his murder trial was to start in Scott County Circuit Court.

Circuit judge Roger Duvall could sentence Caudill to between 50 and 85 years in prison in a hearing Aug. 11 in Scottsburg.

The police investigation found that Turner had been shot in the head  and that Caudill and his girlfriend, 23-year-old Ginger Cox, had been to the shop three times on the day of the crime.

Cox waited in a van while Caudill shot Turner and took cash and other items from the store.

Cox pleaded guilty on June 20 to aiding in a robbery. She will serve 35 years in prison.
