'Making a Murderer' Sheriff's Dept. Targeted by 'Justice for Steven' Bomb Threat

The threat was called in on Wednesday night.

The caller allegedly directed the threat, "Justice for Steven" -- an apparent reference to the show's central character, Steven Avery -- to the Manitowoc County Sheriff's Department, according to the Manitowoc County Police Department.

Avery, who maintains his innocence, was convicted in court and his conviction was upheld. His rape conviction in 1985 was overturned nearly two decades later.

"Making a Murderer" takes a look back at the murder arrest and trial, as well as Avery's bid to clear his name based on the alleged framing. The prosecutor at the time said that the show left out key pieces of evidence and sheriff's department members denied the allegations in court.

Police said that the threat to the sheriff's department stated that there were bombs inside the building and a vehicle with bombs outside the building in the parking lot.

The all clear was eventually given.

The sheriff's department referred the questions to the police department.
