 A Northfield man is sentenced to over two years in federal prison for embezzling $558,000 from ValleyNet. Prosecutors say John Van Butte stole the money from the nonprofit group that was seeking to expand broadband access in the Upper Valley over a period of several years. The 73-year-old Van Butte pleaded guilty to wire fraud in February and was sentenced yesterday in Burlington Federal Court. He was a contract accountant for ValleyNet when the thefts happened.
