A lot of money.

Preston testifies that Liam told him about the money when they were at home, but nothing more came of it.

The next time Liam mentioned the money, Preston tells the jury they were with friends at the Irish pub where he used to work.

Towards the end of his shift, as things were slowing down, Preston testifies that Liam and a couple of friends came by to hang out.

It was the type of money somebody would kill for.

Preston testifies that he doesn't know if their friends knew about the money.

Liam immediately dropped it, and Preston didn't ask any questions.

After that, Preston tells the court they'd only talk about the money whenever he and Liam were alone.

What a huge amount it was, and what they could do with it.

Eventually, Preston tells the jury their conversations changed from daydreaming to scheming.

He testifies that at first, the plan was just to rob her.

They spent weeks planning how to do it.

And then Preston tells the jury something surprising, that he and Liam actually did try to rob Sarah one month before she went missing.

On the witness stand, Preston says he was down the street in a getaway car with his walkie-talkie waiting for Liam's signal.

But that night, they found out Sarah didn't have the money in her house anymore.

She'd put it in a safety deposit box at Kearney Bank.

So they came up with a new plan.

Preston testifies that Liam was going to convince Sarah they should plan a trip to Canada together to get her to withdraw the money.

But the roommates realized they couldn't just take Sarah's money.

If they wanted to get away with it, they needed to do something more drastic.
