Despite the huge success of the first series, you faced criticism for losing sight of the murder victim Teresa Halbach. Have you worked to ensure she is included in Part 2?

M: We invited the Halbachs and Teresa’s friends to participate in Part 2, as we had with Part 1. We want to include Teresa as much as we can in this story, because she matters so much. We have deep empathy for the Halbach family’s loss and it’s actually that empathy that inspires some of the questions we’re asking. We want [the series] to have integrity for her.

Laura: We often talk about how there are no winners in this story. The Halbach family has endured an unimaginable tragedy and our hearts go out to them. There’s pain all around and what we’re asking viewers to do is to spend some time in that complicated place. It’s not simple.

You were accused by the former prosecutor Ken Kratz of not including all evidence and of being biased toward Avery and Dassey. Did you want to address that in Part 2?

M: We’re not taking our cues from viewers. We’re following through on a story that we structured and laid out in Part 1 and continuing to follow it in the next chapter. L: What was interesting is one of the main accusations [Kratz] pushed at us is his claim that we left out what he called “the significant piece of evidence in the hood latch” [Avery’s sweat was allegedly found on the latch of Halbach’s car]. What happened organically was that the new attorney Kathleen Zellner thoroughly looked into that herself. So we documented her addressing the issue, but I wouldn’t say our inclusion of that was motivated by any particular statements by the prosecution.

What about omitting Avery’s history of aggression towards women [his ex-fiancée has accused him of violent and abusive behaviour]? Was that a conscious decision in how to portray him?

M: No. Those were allegations by the former prosecutor to paint Steven as a “bad guy”. That was not part of our enquiry because that was not part of the legal process. Our story was to look at the investigation and prosecution of these two men and ask, is it fair?

Why Making A Murderer creators won’t let Teresa Halbach be forgotten
