I'm always, I mean, I'm usually the last one out.

And at the autopsy, the medical examiner recovered portions of two .22 caliber slugs.

Armed with that information, the detective started to develop a theory about the final moments of Stephen Schwartz's life.

So this is not the actual staircase where the crime happened or the same house, but it gives us an idea of what happened that day.

Okay.

So walk me through what you believe happened.

That's when he was shot in the head, but it was more of a surface wound.

He was still alive?

Diebel believes the doctor was awake and helpless as the killer finished him off with that cut to the neck.

It was a lot to take in.

A cruel killing.

A grieving widow.

I think we can, yeah.

And as detectives would soon learn, a case and a family with plenty of secrets.

After he was murdered, a story broke in the papers that totally stunned me.

I would have never ever in my life thought I'd run into somebody that could be this devastating to the family.

As forensic teams combed through the palatial home of Rebecca and Stephen Schwartz, Dr. Schwartz's son, Carter, was half a world away.

He was heading back home from a trip to Asia.

Well, sneaking back.
