In one of the videos, he says that it was recorded on an SD card, so they were able to upload those.

review them, get them translated, and they wanted to enter it into the record.

I think they want to demonstrate that even though the perpetrator is deceased, they continue to try to seek information and therefore justice in some way for the families of the two students who were killed.

And the other students who were injured, and of course, the MIT professor, the brilliant professor who was the father of young children, married, that he was assassinated at close range.

That's another thing, Juliet, that's interesting when you read this transcript carefully.

He talks about being injured in the eye after he shot the professor at close range.

And he's so concerned about his own injury.

And he shows absolutely no remorse or concern about the lives lost and the injured people injured by his gunshot.

It's just a truly chilling...

Just chilling evidence of that kind of narcissism and self absorption and having covered a lot of cases.

It is not uncommon for that perpetrator of these cold blooded murders to be so consumed thinking about themselves and not showing remorse for victims, but

That really did stand out to me in reviewing these transcripts.

Well, they say they really want to find a motive.

Here's what they've told us and what we learned from our own reporting is that the MIT professor and this shooter had studied together in the late 1990s.

So more than 25 years ago, they were in the same exact academic physics track at a university in Portugal.

So they definitely knew of each other.

But fast forward, we don't have a timeline of the two of them interacting.

We don't have his internet searches.

Was he obsessed with this professor?

Was he searching him, reading articles as the professor was gaining more and more respect and fame really for leading this prestigious laboratory of 250 scientists at MIT and doing really important groundbreaking work.
