A former UW-Madison student who faked a mental illness in order to escape punishment for child pornography distribution was sentenced Monday to 12 years in federal prison. From the time of his arrest in 2010 until pleading guilty in November, Matthew P. Hendrickson, 23, of St. Cloud, Minn., had blamed his downloading and extensive sharing of child pornography on visual and auditory hallucinations. Hendrickson was expelled from UW-Madison in fall 2010.
