Ashley Schwamm

But now she was dead, and detectives needed to know more about that affair.

When you hear a detail like that, how does that now factor into your view on this case?

With the murder investigation into Ashley Schwamm accelerating, Detective Glassford and his team created a war room, a whiteboard at the center.

One thing on their to-do list was speak to Ashley's former boss, Steve McDonald, the man she'd had the affair with.

They learned he'd since gotten divorced.

Yeah, I mean, he could be very angry with her.

She broke off the relationship to try to make things work with James.

Do you bring him in?

Is that the next step?

What was his story?

They also questioned McDonald's now ex-wife, Alexandra.

She was angry with Ashley.

She called her out on this Bahamas trip, told her to tell her husband or else she would.

Literally when this happened.

Detectives were being careful not to have tunnel vision, looking into every possible suspect.

They'd even checked out the contractor James said Ashley had a dispute with.

So detectives decided to take another look at James.

His story about where he was at the time Ashley's SUV went off the road and burst into flames never changed.

And he accounted for every moment he was out that morning.

So just walk me through the route and sort of just trace it, okay, if you can.
