A Wabash County man was sentenced to 50 years in prison late last week for the killing of his girlfriend. Court records show that 34 year old Rueben Corzine of Mt Carmel was given the term during an appearance Friday in Wabash County Circuit Court. He had originally plead guilty to First Degree Murder in the January 2020 stabbing death of 41 year old Jennifer Phelps at their Cherry Street residence, but was allowed to change his plea to Guilty But Mentally Ill in order to receive treatment for mental illness while in prison. He must serve 100% of the sentence and will have three years of Mandatory Supervised Release after getting out. He does have 30 days to appeal.
