Ken Kratz, the lawyer whose prosecution of Steven Avery and Brendan Dassey was chronicled on Netflix’s wildly popular docu-series “Making a Murderer,” is writing a book about the case.

Kratz told WBAY-TV, ABC’s Green Bay, Wis. affiliate, that he’s penning a book to give a voice to Teresa Halbach, the woman who Avery and Dassey were ultimately convicted of murdering. He admitted to the outlet that he’s felt obliged to defend the Halbach family since the Dec. 18 release of the documentary and is “finally grateful to tell the whole story.”

“The one voice forgotten to this point is Teresa Halbach,” said Kratz, the former district attorney of Wisconsin’s Calumet County.

Filmed over a 10-year period, “Making a Murderer” documents Avery’s 1985 imprisonment, his later exoneration for the crime in 2003, and his subsequent controversial arrest and trial for the 2005 murder of Halbach, a photographer who was reportedly last seen on his property.

“Making a Murderer” has become a true crime sensation, inviting the unveiling of new information and igniting a widespread media debate about whether Avery is guilty of Halbach’s murder or if he was framed for the crime. At the onset of the doc’s ascent to popularity, petitions were created urging President Barack Obama to pardon Avery. HLN’s Nancy Grace devoted a special broadcast to presenting an “avalanche of evidence” against Avery, while “Making a Murderer’s” creators have publicly defended him.

According to Netflix’s chief content officer Ted Sarandos, the ongoing developments in the story may be reason for a second season of the true-crime hit.

“The story is still unfolding, so we’ll certainly take a look at it,” Sarandos said last Sunday at the TCA winter press tour.
