they do finally discover Nanette's .40 caliber handgun.

It's the same one that she carried with her everywhere.

It's the gun they're thinking that Nanette might have used.

And so the lead investigators start coming up with another theory.

Could Nanette have lit the fire and then died by suicide?

It's just a hunch at this moment.

Obviously, they have to start collecting all these weapons so they can really try and test them.

In the meantime, investigators turn to Nanette's friends and family to try to understand her behavior and maybe her mindset before she died.

Absolutely not.

I mean, she was a huge animal lover and this was baby kitty Smokey and Harley.

There's no way.

So at this point, investigators need to evaluate if Nanette could have indeed started the fire and then taken her own life.

Was this a cover-up?

And they knew that if Nanette was alive while the fire was burning, there would be signs of that in her air passages.

And that brings us to our third clue.

Dr. Preston examined Nanette's throat and lungs during the initial autopsy, and he found no soot or particulate matter anywhere.

In her airways.

Immediate red flag.

Immediate.

I mean, huge.
