Kate Snow

Her cause of death was ruled undetermined after an autopsy.

There were no obvious injuries.

You believe this was a murder.

And correct me if I'm wrong, was she not found in the passenger seat of the pickup truck?

Yes, she was.

Okay, so how is this undetermined if, like, someone can't drive themselves into a lake in the passenger seat?

While they're buckled in.

So, I mean, it's either murder or someone had an accident and left her there.

I mean, there's not a whole lot of options there, but you truly believe this was murder.

Oh, yes, definitely.

And so it's been over eight years since Olivia went missing and we don't have an arrest.

And even the FBI has gotten on board.

Well, the FBI was on board from the very beginning because if it's a homicide, then this is a major crime which falls under their jurisdiction.

And then a few years back, I did inquire with the FBI and I gave them some information.

Do you have a message for the FBI or for tribal police about what they could be doing?

And we should say, Lissa, we did reach out to the FBI.

They told us they continue to diligently investigate Olivia's disappearance and death, and they're offering a reward of up to $10,000 for information leading to an arrest and conviction in this case.

I mean...

In the end, Olivia and her children still deserve some type of justice.

Lisa, thank you for all your work.
