An Amherst man will spend two months in jail following sentencing on drug convictions Monday in Portage County Court. 64 year old Lonn Gunderson in October pleaded no contest to possession of marijuana with intent to deliver, and maintaining a drug trafficking place. Police last February discovered a pot-growing operation in the basement of his home, with 57 growing plants. He will serve 40 days of his sentence on electronic monitoring. Gunderson was also placed on two years probation.
