Steven Avery was moved late last month from a maximum-security prison in Waupun to a medium-security prison about 10 miles away in Fox Lake. Avery, 59, has been serving a life sentence since being convicted of killing Teresa Halbach, a 25-year-old photographer who disappeared in 2005. His story was featured in the Netflix docuseries "Making a Murderer," which cast doubt on the motives of police and left many viewers with the impression that Avery and his nephew, Brendan Dassey, were wrongfully convicted.
