CASS COUNTY, Michigan — A man was sentenced to prison after he was found at a Michigan sawmill with a walnut tree that did not belong to him. Trever Wallace was sentenced to three years and two months up to 10 years in prison for his criminal concealment of a fully mature walnut tree, Cass County Prosecutor Victor Fitz said. …The tree’s owner was able to locate it at the sawmill before Wallace could profit from it, Fitz said. The defendant pleaded guilty as charged to larceny over $1,000. On Friday, Cass County Assistant Prosecutor Jason Ronning asked for prison time due to the defendant’s nine prior felony convictions and two misdemeanor convictions, including thefts. Fitz did not know the current state of the tree.
