Honestly, it's kind of novel that you would get an undetermined.

We get a whole lot of who done it, but there has to be very special circumstances for

the cause of death to be truly undetermined.

We've got to prove that there has been a murder before you can convict somebody of murder.

I'm Scott Weinberger, investigative journalist and former deputy sheriff.

I'm Anna Sige Nikolasi, former New York City homicide prosecutor and host of investigation

discoveries to conviction.

And this is an out of me of murder.

Cause of death, we've all heard that phrase.

In fact, it may be one of the few things that everyone, all of us on this earth, have

in common.

We will all eventually have a cause of death of our own.

But it is also the first step in any homicide investigation determining how somebody died.

Today's case takes us south to Alabama where we spoke to prosecutor Timothy Dauphin.

Tim is the chief trial attorney in Madison County's District Attorney's Office in Huntsville,

which is a city of about 200,000 people located about a half hour drive from the Tennessee

border.

To be completely honest, when I was at about high school, somebody said, you should be

a lawyer, you know, and I turned around and said, oh, man, you can argue and give speeches

for a living.

I didn't realize they paid people to do that.

That's a great job.
