Beth Dutton

So this is, I guess, what is my first installment of my video diary.

Inside that suitcase was the torso of a white male.

His head and arms were still attached.

My name is Beth Dutton.

I am a forensic specialist supervisor.

I've been in forensics for 17 years.

This was one of the most brutal crimes that I had seen.

The fact that somebody can dismember another human being like a piece of meat is just something that's very disturbing.

My brother had the kindest heart of any person that I've ever known.

He always had a smile on his face.

You were always happy to be with him.

When I heard how my husband was killed, I was in complete disbelief.

I did not kill the father of my children.

I did not kill my husband.

Everybody says, you just got to hold on.

You just got to hold on.

I don't know if I can anymore.

Three months after the body of Bill McGuire was found in the Chesapeake Bay, his beautiful wife was not only a widow, Melanie McGuire was also a murder suspect.

I'm just kind of numb at this point, and when the numbness subsides, it's sort of interspersed with terror, so...

48 hours gave Melanie a camera to document her innermost thoughts and fears.
