MOTHER AND SON IN CUSTODY IN WYOMING; CHARGED IN CONNECTION WITH MURDER OF BLANCHARD MAN
OKLAHOMA CITY – A 47-year-old woman and her 26-year-old son are in custody in Wyoming charged with the murder of 56-year-old Michael “Andy” McGuffee. Debbie Senft and Zachary Mussett, both of Texarkana, Texas, are currently in custody in the Sweetwater County, Wyoming Detention Center awaiting extradition to Oklahoma to face charges related to the murder of McGuffee.
On October 15, 2021, McGuffee’s wife was contacted when he did not show up for work and she sent a family member to check on his welfare. When that family member arrived at the residence in the 8300 block of Garvin Drive and saw signs of a fire, he contacted the Blanchard Police Department. After officers arrived at the scene and found McGuffee deceased, the Blanchard Police Department requested Oklahoma State Bureau of Investigation (OSBI) 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 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 (KBI) went and collected the evidence from the pawn shop on behalf of the OSBI. A few days later, agents recovered the pickup truck at a car wash off I-35 and 89th Street in Oklahoma City.
The investigation then led agents to Wyoming. Working with the Wyoming Division of Criminal Investigation (DCI), Senft and Mussett were located 15 miles east of Rock Springs, Wyoming on I-80. The Wyoming Highway Patrol pulled over the moving truck Senft and Mussett were driving and agents with Wyoming DCI took the pair into custody.
Senft, who is McGuffee’s half sister, and Mussett are both charged with one count of Murder in the First Degree and one count of Arson in the First Degree and are being held without bond in Wyoming.
In addition to KBI, Wyoming DCI, and the Wyoming Highway Patrol, the OSBI would like to thank the Oklahoma State Fire Marshal’s Office and the Goodland, Kansas Police Department for their assistance with the Investigation.
