DNA doesn’t lie—at least, that’s what we’re told. But in Steven Avery’s trial, the way evidence was collected, handled, and explained leaves you scratching your head.

Today, we hear from the state’s DNA expert, John Ertl. He walks the jury through his role in collecting and documenting key evidence: from Teresa Halbach’s RAV4, to suspicious stains in Steven’s garage, to burn barrels, a golf cart (another distraction?) and even the car crusher that has become weirdly infamous.

But here’s the issue it was Ertl's team, the field response team who was called in to do the professional processing. Yet, when they got to Avery's garage, it had already been done. Not by them. By who then?

Why did investigators raise the car crusher ramp only to be told by Fassbender, “we don’t need that anymore”? Did the field response team really have to investigate there or was it a distraction because at the same time, Teresa's RAV4 was being moved into the trailer.

By the way, it was an enclosed trailer. Who was in the trailer with the car? Do we even know?

This is the first of a couple Episodes where Ertl is on the stand. This is Part 1 - the prosecution questions him. In the next episode, the defense gets a stab at him.
