Elisabeth Gunter, 43, and her boyfriend, Dennis Woodward, 45, both of Norwood, are set for a preliminary hearing on Feb. 10 in Howell County Circuit Court.
Both are facing four felony charges in Dishneau's death, including first-degree murder, armed criminal action, first-degree robbery and first-degree tampering with a vehicle.
Woodward is represented by attorney Donna Kay Anthony of West Plains. Gunter is awaiting appointment of a public defender.
Both are accused of breaking into Dishneau's Highway 160 home, stabbing her to death, stealing cash and electronics and leaving in Dishneau's Jeep.
Court records indicate each has accused the other of stabbing Dishneau in the neck. Both allegedly admitted robbing Dishneau to get money for a downpayment on some land.
