So you, your sister Claudia, and Paul got in the car to head to this concert.

When you woke up, did you know exactly what happened to Paul and Claudia?

May 2016, it's dark and late at night.

Paul Cook is driving his close friend Claudia and her sister Adriana back from a concert in the nearby town of Morelia.

So late that night after the crash, Claudia was found dead at the scene.

But then the other two were taken to the hospitals.

Peter first to this private hospital and then Adriana was taken to a public hospital.

You were in a coma for 15 days.

Do you remember exactly how you felt when you got that word that your sister died?

So this is the way that families notify the others and honor those that died when somebody dies?

When you heard that Paul was not badly wounded, what did you think at that point?

So one was killed, one was badly paralyzed, and he was just limping.

For Claudia's family, the mystery that was surrounding Paul began at 4.30 in the morning, just hours after the crash.

They were called into the district attorney's office and presented with this remarkable document to sign.

It's stunning to us that this exists, that they wanted to make something legal in a document that relieved Paul from this crash.

Sí.

Were you able to read it at all when it was written?

We pressed for more information to better understand the origin and the purpose of this document.

Ultimately, we heard back from the Michoacan Attorney General's Transparency Unit.

They stated that the document is part of the investigation and they're aware of the incident.
