In the quiet town of Willard, Missouri, a tragic story unfolded on November 14, 2020, ending the lives of 30-year-old Brianna Sproul and her 28-year-old fiancé, Alex Chute. The couple was discovered shot to death on the front porch of their home, an event that initially puzzled investigators but was quickly determined to be a targeted double homicide.
The investigation into the brutal slayings soon uncovered a sinister plot rooted in a bitter custody dispute.
Suspicion fell upon Alex Chute's ex-wife, Theresa Cox, who was embroiled in a contentious battle with Chute over their young daughter. Investigators alleged that Cox orchestrated the murders, enlisting the help of her new boyfriend and two other individuals to carry out the crime.
According to court documents and police reports, Cox convinced her 20-year-old boyfriend, Duncan 'Mixxi' Bogle, to be the triggerman in the fatal shootings. Another accomplice, a coworker of Cox's named Matthew Plumb, was accused of providing an alibi and assisting in the disposal of the murder weapon. Plumb's nephew, Therin Plumb, was also implicated and charged with evidence tampering for his alleged role in getting rid of the gun.
Following a thorough investigation, all four suspects were taken into custody. Theresa Cox and Duncan Bogle, who had fled to San Francisco, were arrested and extradited back to Missouri to face charges. In the end, both Cox and Bogle pleaded guilty to their roles in the murders. They were each sentenced to serve consecutive life sentences, ensuring they would spend decades behind bars. Matthew Plumb also pleaded guilty to lesser charges for his involvement and received a prison sentence. The charges against Therin Plumb were eventually dismissed in exchange for his cooperation with the prosecution.
