Mom, son killed a man and set his home on fire, police said. Then they pawned the victim's belongings.

A mom and son are accused of killing a man and setting his home on fire. They then pawned some of the victim's belongings in several states, police said.

Debbie Senft and Zachary Mussett, both of Texarkana, Texas, were charged in connection to the killing of Michael "Andy" McGuffee in Oklahoma. The two are currently in custody in the Sweetwater County, Wyoming, jail.

McGuffee was Senft's half-brother.

On Oct. 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 well-being. Officials said family members saw signs of a fire at a home and contacted police in Blanchard, Oklahoma.

Investigators determined McGuffee was the victim of a homicide when they discovered the fire was intentionally started, and many items were stolen from the residence, including McGuffee's pickup truck, according to the Oklahoma State Bureau of Investigation.

Kansas Bureau of Investigation Agents went and collected evidence from a pawn shop on behalf of their Oklahoma counterparts after they reportedly discovered items stolen from McGuffee were pawned in Salina, Kansas, earlier this week.

A few days later, agents found the pickup truck at a car wash off I-35 and 89th Street in Oklahoma City.

The investigation then led agents to Wyoming, where the Wyoming Division of Criminal Investigation found Senft and Mussett 15 miles east of Rock Springs, Wyoming on I-80. The Wyoming Highway Patrol took the pair into custody.

Senft and Mussett were both charged with one count of first-degree murder and first-degree arson. The two are being held without bond in Wyoming.
