The Minnesota Supreme Court has denied the appeal of a former Mankato man in prison for killing his estranged wife. Joel Marvin Munt was convicted of killing Svetlana Munt in Mankato’s Rasmussen Woods Park in March of 2010. A 1st-degree murder conviction is automatically appealed to the state Supreme Court under Minnesota law. Munt’s attorneys argued that there was bias from both the judge and jury over comments made as part of his insanity defense. The Supreme Court’s opinion rejected that claim. The Court also rejected Munt’s arguments that the trial should have been moved because of pre-trial publicity. Also dismissed were arguments that hearsay evidence was admitted, that witnesses were tampered with, that Munt received ineffective counsel, and that the court system was corrupt. Munt was sentenced to life in prison for the murder.
