Steven R. Johnson fatally shot and dismembered his wife in their St. Paul home on Sunday after she announced plans to leave him and take their 18-month-old son.
Johnson, 34, used a saw to dismember Manya J. Johnson in the couple's shower. He then placed the 32-year-old woman's body in several plastic bins and stored them in a friend's garage in White Bear Lake, according to second-degree murder charges filed against him on Wednesday in Ramsey County District Court.
According to the charges, Johnson confessed, telling police he and his wife argued Sunday. He said he had been drinking, and shot Manya in the head with a handgun. He said he cleaned the house to hide evidence.
The friend in whose garage Johnson put the bins was unaware of his actions, the complaint said, but Johnson later told him what he'd done. The friend alerted White Bear Lake police about 3 p.m. Monday, who notified St. Paul police.
The killing shocked neighbors and friends, who considered the Johnsons "the perfect couple" and good neighbors.
However, Anoka County court documents from his 1996 conviction for aiding and abetting criminal sexual conduct describe a troubled teen who had chemical dependency issues. A psychologist diagnosed the 18-year-old as "particularly defective in his capacity for empathy" and as having "a pathological sexual adjustment that is not likely to be improved very much by the time he leaves prison."
According to Anoka County documents on the crime, Johnson and two friends tricked the woman into climbing into Johnson's car in Coon Rapids. They drove to an isolated area near Sand Creek Park, where his friend, Kyle D. Scott, also 18, grabbed the woman and Johnson handcuffed her.
The second friend fled, according to the complaint. Johnson and Scott tore off the woman's clothes, taped her mouth shut and sexually assaulted her multiple times. They also simultaneously raped her. Johnson threatened to kill her, and implied that he had a gun.
