ST. PAUL (AP) — A St. Paul man accused of dismembering his wife now faces a first-degree murder charge.

A Ramsey County grand jury Tuesday indicted 35-year-old Steven Roger Johnson on charges of first-degree murder and second-degree intentional murder.

Johnson was previously charged with second-degree murder in the death of his wife, 32-year-old Manya Jewel Johnson.

Charges allege Steven Johnson fatally shot and dismembered his wife in their home Jan. 6 after she said she planned to leave him and take their son. The complaint alleges Johnson placed her remains in plastic bins and stored them in a friend's garage in White Bear Lake.

The complaint says the friend alerted police after Johnson told him what he'd done.

Johnson is scheduled to appear in court Wednesday. His attorney had no comment.
