From New York Times, I'm Michael Borrow. This is Adali.

Today, the mass shooting that occurred in me last week,

killing 18 people, was the country's deadliest of the year.

It may also have been one of the most avoidable.

My colleague, Nicholas Bogle-Borrow's,

on why so many warnings about the suspected gunman,

from so many people, failed to stop it.

It's Thursday, November 2nd.

Nick, in the days since this awful mass shooting in Maine,

you have been trying to reconstruct the warning signs.

That something was very wrong with the suspected shooter.

So tell us about what you have been finding.

Yeah, so in the days after this attack,

we've received a bunch of documents that show a series of

troubling interactions with the suspect whose name is Robert Card.

He's a 40-year-old Army reservist.

And the documents show that these warnings concerned his deteriorating mental health,

rising paranoia and anger.

And they came from pretty much every part of his life.

But as we now know, none of those warnings prevented this mass shooting.

Well, Nick, where should we start in the story of those warnings?

You mentioned that they go back many months.
