A pretrial hearing was set this morning for a Texoma man charged with murder, but has since been re-scheduled.
Police say Tommy Ray Morrow is accused of stabbing his mother Helen Clark to death, then called 9-11 to say she passed away.
When police arrived at the scene back in April, they found Clark with lacerations to her wrists and neck and a stab wound to her chest.
Detectives say Morrow insisted there was no way anyone could have got into the house and there were no signs of forced entry.
Police also found a possible murder weapon at the scene.
