And then she, very shortly after, had Jake cremated.

So it was really a real 180 when prosecutors charged Susan with murder.

How could they argue the shooting was a homicide and not a suicide?

At Susan's first trial, the prosecution told the jury that Susan staged the scene to fool investigators.

They argued that things like the bullet trajectories and the position of Jake's body proved that someone else had shot him.

When did this idea of alleged poisoning enter the picture?

It really started with Jake's family.

They found the suicide story fishy from the outset.

Jake's son said he had been with his dad just before the shooting, and he told us that his dad seemed in a good mood.

They were talking about the future.

And it all made the family dig deeper into their suspicions.

They were suspicious of Susan from the get-go.

They were really suspicious of Susan from the very beginning.

Jake's family told us that Susan tried to isolate him from the family.

She took over his finances and his email accounts.

That's something that Susan denies doing.

And one of the big things that had really stood out to them is that their dad, since he had married Susan, seemed to be getting sicker and sicker.

Can you walk us through the timeline?

Yeah.

So about a month or two into their relationship, Jake had a heart attack and Susan became his caregiver.
