There's been a lot of talk about Netflix's Making a Murderer leaving out details from the trial (don't even attempt to do sleuthing on Reddit, because you will fall down a rabbit hole for days). We thought we'd heard it all. But the bombshells dropped during tomorrow's Investigation Discovery special Steven Avery: Innocent or Guilty? are revelatory. They even have an answer for the test tube of Steven Avery's blood that appeared to be tampered with. The special airs Saturday night at 9 p.m. Here are the top 5 game changers:

1. An explanation for the suspicious-looking blood vial.

One of the most shocking scenes in the Netflix show is when Avery's trial attorneys, Dean Strang and Jerry Buting, come across a vial of Avery's blood taken during the investigation of a previous rape case. The box containing the blood has an obviously broken seal and the vial itself has a hole in the top. The suggestion was that the Mantitowoc Sheriff's department had broken into the evidence to steal blood to plant in victim Teresa Halbach's car, making Avery look guilty as hell.

But former district attorney Ken Kratz says on the ID special that there's nothing unusual about that vial: All of the purple tubes at that facility have holes in the top. 

"How to you think the blood got in there? The blood gets in there by putting a hole in it," he says. "There's a nurse that was interviewed and said, 'I'm the one who put the hole in there.'"

2. Why was Halbach's blood only found in the trunk of her car?

"We find later when Brendan Dassey is interviewed that he and Uncle Steven, after she was shot in the garage, they, in his words, threw her in the back of the SUV while deciding how to dispose of her body," says Kratz, pointing to Dassey's controversial coerced confession (so, major grain of salt here). "They originally had planned on placing the body in the pond, [but then] believing there wasn't enough water in the pond, Steven Avery carried out the plan to burn her."

3. They found Halbach's phone and camera on the Avery property.

The special produces a photo of the charred remains of Halbach's cell phone and camera, which they say was found in a burn barrel outside of Avery's trailer door. They say this detail was covered in the trial but omitted from the Netflix series.

4. Why Avery used the *67 feature to call Halbach the first 2 times, but not for the final call.

Kratz argues that Avery used the *67 feature when calling Halbach at 2:30 that afternoon to arrange the photoshoot to disguise his identity and phone number. But when Avery called Halbach two hours later, he used his real phone number.

"Importantly, he doesn't use the *67 feature [for the 4:30 p.m. call]. He doesn't have to. Teresa's never going to answer the phone," says Kratz, theorizing that Halbach has already been murdered at this point. "But he's setting up, in my opinion, an alibi. And his first defense is going to be, 'She never showed up.'"

5. The real reason why Avery specifically requested Halbach

Kratz says Avery met Halbach on six earlier occasions and, on the day of the murder, asked specifically for her to come back to his house. And instead of giving his own name, Avery gave his sister's. Which Kratz concludes means that, "Teresa Halbach was targeted by Steven Avery."

But Buting has a different explanation.

"They're trying to make it sound like he was luring Teresa Halbach to his auto salvage yard where he could commit this dastardly crime," Buting says. "She was the only photographer for Auto Trader for that whole area of the state! So, he doesn't say, 'Send Teresa Halbach.' He says, 'Send that woman you had out here to take pictures. We want to put another vehicle in your magazine.'"
