Mike Halbach is in his 12th season as an employee of the Green Bay Packers, and according to the team's website, he "oversees the development and administration of football information systems and guides technical decisions that impact football operations."
He also happens to be one of the main characters in a true-crime documentary series that's currently airing on Netflix.
The name of the show is Making a Murderer, and it follows the story of Steven Avery, who was charged with the murder of Teresa Halbach. Teresa was Mike's sister, and Mike is interviewed continuously throughout the series.
Mike was the family's official spokesperson during the ordeal, and though he chose not to participate in the making of the documentary, the filmmakers showed up at all of the press conferences he held, which is why he appears in the show so frequently.
At least one fan in Green Bay had made a connection with the show at Sunday's game between the Vikings and the Packers, although the fact that the story was set in Wisconsin's Manitowoc County (where law enforcement officials there are portrayed in the series as being less than truthful) was probably the inspiration for this particular sign's creation.
