Cops make arrest in Pizza Hut murder plot that led to killings of young couple found dead on their porch

Police have made an arrest in the apparent murders of a young Missouri couple found shot to death on their front porch last month, and identified two others involved in the alleged murder plot  — including the alleged gunman, who is not yet behind bars

According to court documents obtained by the Springfield News-Leader, investigators believe Theresa Cox, the ex-wife of Alex Chute, who was found dead with his partner Brianna Sproul on November 14, orchestrated a murder plot with two others —  including one of her co-workers at a Springfield Pizza Hut. Matthew Plumb, the co-worker, is in custody in Green County on murder charges. According to the court documents, Plumb did not participate in the shooting, but helped dispose of the murder weapon and provided Cox with an alibi.

Cox’s new boyfriend Duncan “Mixxi” Bogle allegedly carried out the shootings on either the night of November 13 or the morning of November 14, the day Chute and Sproul were found dead at their home in Willard. According to the report, Chute and Cox’s 4-year-old daughter was at the home at the time of the fatal shooting. Police reportedly found her hiding inside the house when they discovered the couple dead, with a gun lying next to them.

The report indicates that the gun at the scene is not the weapon used in the killing. According to the court documents, Cox, with Plumb’s help, falsely reported her gun stolen a few days before the killings. Plumb also disposed of the gun in a creek after the murders, and told police that Cox was at work on the night of November 13, which appears to be untrue.

It is unclear where the suspects got the weapon that was left next to the dead bodies.

As CrimeOnline previously reported, police indicated early in the investigation that Cox and Chute had an ongoing custody dispute involving their 4-year-old daughter.

As of Thursday, Cox and Bogle have not yet been arrested, and police have not yet commented on Plumb’s arrest.

CrimeOnline will provide further updates when more information is available.
