ST. PAUL, Minn. - A Minnesota man convicted of killing his wife is appealing his conviction.

Last November, Jeffery Trevino was sentenced to prison for the murder of 30-year-old Kira Steger.

Trevino's sentence was nearly twice the maximum recommended.

The appeal was filed Thursday in Ramsey County District Court.

Last October, a jury convicted Trevino of second-degree unintentional murder and acquitted him of second-degree intentional murder.
