The Netflix documentary series "Making a Murderer" has brought national and worldwide attention to the 2007 trial of Steven Avery, convicted of killing Teresa Halbach in Manitowoc County.

Milwaukee Journal Sentinel reporter Tom Kertscher, who covered Steven Avery's weekslong 2007 trial, is interviewed briefly in the first episode of the series and can be seen periodically in later episodes during news conferences with the attorneys in the case.

You can find Kertscher's original coverage of the trial here, and he set out this week to watch the documentary himself and is tweeting his reactions to each episode as he watches them. You can get a sampling of his tweets below.

Avery had spent 18 years in prison for rape until being released in 2003 when DNA showed another man had committed the crime. He was pursuing a lawsuit against Manitowoc County officials when he was arrested in Halbach's killing in 2005.

His defense in the homicide case argued at trial that Manitowoc County investigators planted evidence to frame Avery for the killing, but a jury found him guilty of first-degree intentional homicide on March 18, 2007. He was sentenced that June to life in prison.

I'm planning to live tweet some of my reactions to #MakingAMurderer, which I'll start watching in a few minutes. — Tom Kertscher (@KertscherNews) January 4, 2016

#MakingAMurderer Episode 1: Surprised how slowly it starts. But maybe that's because I covered the murder and Steven Avery's trial. — Tom Kertscher (@KertscherNews) January 4, 2016

#MakingAMurderer Episode 1: Surprised by early focus on Steven Avery's nephew, Brenda Dassey. Wish I'd covered Dassey's trial. — Tom Kertscher (@KertscherNews) January 4, 2016

#MakingAMurderer Episode 1: Portrayal of Dassey lawyer as corrupt very disturbing. But how pivotal was his confession in Avery conviction? — Tom Kertscher (@KertscherNews) January 4, 2016

#MakingAMurderer Episode 1: I understand sympathetic treatment of Avery, his family. Want to see treatment of evidence used against him. — Tom Kertscher (@KertscherNews) January 4, 2016

#MakingAMurderer Episode 2 focuses on police targeting Avery in sex assault, not Gregory Allen. My story then: https://t.co/z7V6pYBmLA — Tom Kertscher (@KertscherNews) January 4, 2016

#MakingAMurderer Episode 2: Cops targeting Avery in '85 sex assault case is clear. That suggests they also did in '05 Halbach murder? — Tom Kertscher (@KertscherNews) January 4, 2016

#MakingAMurderer Episode 2 makes you wonder: If Avery didn't kill Halbach, why did he do so many media interviews before his arrest? — Tom Kertscher (@KertscherNews) January 4, 2016

#MakingAMurderer Episode 2: So far, the film's depiction of prosecutor Ken Kratz's demeanor is as I recall it. — Tom Kertscher (@KertscherNews) January 4, 2016

#MakingAMurderer Episode 3: In considering whether Avery was framed, fair to say law enforcement have strong desire to back each other up — Tom Kertscher (@KertscherNews) January 4, 2016

#MakingAMurderer Episode 3: Halbach car on Avery property, bones in his burn pit, his DNA on her car & key--strong preliminary evidence. — Tom Kertscher (@KertscherNews) January 4, 2016

#MakingAMurderer Episode 3: DA Kratz gave media detailed account of Dassey finding Avery with shackled Halbach. Was Dassey that detailed? — Tom Kertscher (@KertscherNews) January 4, 2016

#MakingAMurderer Episode 3: If local cops framed Avery, did state DOJ lawyer and investigator and asst Milwaukee DA on case have no idea? — Tom Kertscher (@KertscherNews) January 4, 2016

Halfway into #MakingAMurderer, hard not to wonder if Avery did not kill Halbach. And yet the evidence against him at trial was strong. — Tom Kertscher (@KertscherNews) January 4, 2016

@IsabelGreeny The point is, if your only exposure to the case is Netflix, you've only gotten 1 (admittedly compelling) side of the story. — Tom Kertscher (@KertscherNews) January 4, 2016

#MakingAMurderer Episode 4: Dassey lawyer Kachinsky comes across as oddly eager to be on case. I recall him as eager to talk to media. — Tom Kertscher (@KertscherNews) January 5, 2016

#MakingAMurderer Episode 4: Doesn't allay other evidence vs Avery, but defense investigator orchestrating Dassey confession--astounding. — Tom Kertscher (@KertscherNews) January 5, 2016

@layman_chad Well, that was only one statement. And we in the media might like to think all our coverage is seen by everyone, but not so. — Tom Kertscher (@KertscherNews) January 5, 2016

#MakingAMurderer Episode 4: What-ifs such as, If Avery killed her, why didn't he crush her car in salvage yard? -- not too persuasive. — Tom Kertscher (@KertscherNews) January 5, 2016

#MakingAMurderer Episode 4: Sheriff refuting allegation that cops framed Avery--"It would have been much easier just to kill him." Wow. — Tom Kertscher (@KertscherNews) January 5, 2016

#MakingAMurderer Episode 4: Hard for defense to say Avery not bright AND say not crushing Halbach's car indicated he didn't kill her. — Tom Kertscher (@KertscherNews) January 5, 2016

After 4 hours of #MakingAMurderer, I remember how spending years covering a murder case seeps into your pores, alters your dreams. Scary. — Tom Kertscher (@KertscherNews) January 5, 2016
