Andrew Colborn, a now retired sheriff, has claimed the hit Netflix documentary suggested he planted evidence to frame accused murderer Steven Avery.
In a statement released to Variety, Griesbach said: “His reputation and that of Manitowoc County, itself, has been severely and unjustly defamed.”
“He is filing this lawsuit to set the record straight and to restore his good name,” he continued.
The suit also stated that Colborn has suffered a loss of income as a result of series.

Netflix have not yet commented on the defamation suit.
The first season of Making a Murderer looked at the case of Steven Avery – a man who was wrongly convicted and exonerated for rape, and then later convicted for the murder of 25-year-old photographer, Teresa Halbach.
Avery’s teenage nephew, Brendan Dassey, was also convicted for his alleged role in the crime.
The ten-part documentary series was filmed over 10 years and its 2015 release generated a huge amount of buzz around the case, with viewers fiercely debating whether Avery was actually guilty or wrongly convicted once again.
After the first season aired, both Avery and his nephew Dassey launched appeals.
In 2016, a judge ruled that Dassey should be released from prison. But then another judge ruled that he should remain in prison.
