MINNEAPOLIS — A Minnesota man was charged Wednesday with shooting his wife after an argument, sawing her body into pieces and hiding her remains in plastic bins in a friend’s garage.

Steven Roger Johnson, 34, of St. Paul, was charged with second-degree murder in the death of his wife, Manya Jewel Johnson, 32. According to the criminal complaint, Johnson admitted that he killed his wife on Sunday after she told him she was leaving and taking the couple’s 18-month-old son with her.

Police said the couple’s child was in the home at the time of the slaying.

Johnson allegedly told police he had been drinking when he shot his wife in the head and “used a saw to dismember her body in the shower and he placed her in several plastic bins,” the complaint said.

Johnson said he then cleaned up his home to hide any evidence and took the bins to his friend’s garage in the St. Paul suburb of White Bear Lake.

The friend didn’t know what had happened until Johnson told him later, and the friend called authorities.
