Crime / Making a Murderer Threat Targets Making a Murderer Sheriff's Office Caller threatened Manitowoc County bombing By Newser Editors and Wire Services Posted Feb 4, 2016 1:23 AM CST Copied In this March 13, 2007 photo, Steven Avery listens to testimony in the courtroom at the Calumet County Courthouse. (Morry Gash) Authorities say a caller who phoned in a bomb threat to a Wisconsin county sheriff's office made an apparent reference to "getting justice" for the man at the center of the Making a Murderer documentary. A statement from the Manitowoc Police Department says a male caller made the threat around 6:40pm Wednesday. It says the caller described bombs inside the Manitowoc County sheriff's office building and a vehicle outside with explosives. The statement says the caller mentioned "getting justice for Steven," what it describes as an apparent reference to Steven Avery, the Wisconsin man whose prosecution in a 2005 killing was the centerpiece of the Netflix series. The series questions Avery's treatment and suggests the possibility Manitowoc County sheriff's deputies planted evidence. Authorities found no suspicious device and deemed the area all clear. (The series has changed Manitowoc County, where officials say they now have to deal with a lot more "cussing.") Report an error
