Investigators with the Madison County Sheriff's Office said Elmore and Adkins got into a fight over alcohol. Elmore is accused of stabbing Adkins, then suffocating her with a blanket in June 2013.

Deputies found Elmore waiting for them calmly inside the home.
Investigators say they found a suicide note saying Elmore had killed Atkins and himself. They also found a noose in the back yard of the home, and a ladder.
Adkins was found face up in bed. They believe she was killed on a Sunday and found the following Tuesday.
Investigators say Elmore confessed several times on tape.
