In the early morning hours of July 6, 2021, a single gunshot killed 57-year-old Michael Vincent inside his Magna, Utah martial arts studio and residence, Vincent’s House of Goju on Main Street. His wife, Cynthia Vincent, called 911 and admitted to shooting him, saying she acted in self-defense after he had assaulted and strangled her. Officers found a revolver beside Michael’s body and noted a large scratch under Cynthia’s chin but no other visible injuries; investigators reported the evidence did not support her self-defense claim.

Police records show officers had been called twice to the couple’s home in the previous year for domestic disputes, with no arrests. Prosecutors later argued Michael was leaving through the front door when he was shot in the side of the head and cited security footage showing the couple interacting normally the day before, including a kiss two hours before the 911 call. Cynthia’s account of the shooting changed between interviews, and six months after the death she was charged with murder; she ultimately pleaded guilty to reduced manslaughter charges and was sentenced in December 2022.

Did anyone in Magna know Michael or Cynthia and recall their relationship or the night of July 6, 2021?
