A mother and son sought in connection with an Oklahoma murder were arrested near Rock Springs this week, according to the Oklahoma State Bureau of Investigation.

Debbie Senft, 47, and Zachary Mussett, 26, both of Texarkana, Texas, are currently in custody at the Sweetwater County Detention Center and are awaiting extradition to Oklahoma to face charges related to the murder of 56-year-old Michael “Andy” McGuffee, the OSBI announced Friday.

Both the mother and son have been charged with one count of first-degree murder. Senft, who is McGuffee’s half-sister, and Mussett are being held without bond.

On Oct. 15, McGuffee’s wife was contacted when he did not show up for work in Blanchard, Oklahoma. She sent a family member to check on him.

When that family member arrived at the residence and saw signs of a fire, he contacted the Blanchard Police Department. After officers arrived at the scene and found McGuffee’s body, the Blanchard Police Department asked for the Oklahoma State Bureau of Investigation’s assistance with the investigation.

When OSBI agents arrived on the scene, they determined McGuffee was the victim of a homicide.

While agents processed the crime scene, it was discovered that a fire had been started intentionally and many items were stolen from the residence, including McGuffee’s pickup truck.  

Early this week, agents discovered that items stolen from McGuffee were pawned in Salina, Kansas. At that point, the Kansas Bureau of Investigation went and collected the evidence from the pawn shop.

A few days later, agents recovered the pickup truck at a car wash in Oklahoma City.

The investigation then led agents to Wyoming.

Senft and Mussett were located 15 miles east of Rock Springs on Interstate 80 this week. The Wyoming Highway Patrol pulled over the moving truck Senft and Mussett were driving and agents with Wyoming Division of Criminal Investigation took the pair into custody.
