It's still right now hard for me to believe that she's not here.

I don't think it's a day goes by that I don't think about Angela.

You know, it's just kind of blame myself that I wasn't there to help protect my sister.

She didn't deserve to die like that.

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

I'm Anna Siga-Nicolasi, former New York City homicide prosecutor and host of investigation discoveries through conviction.

And this is Anatomy of Murphy.

When I think about today's case, it's more in the big picture that I see it.

Every case is tragic, but certain ones really strike a nerve.

And this is one of those for me.

Today's story takes us to Dearfellabeech, Florida, which is just a couple of miles north of Fort Lauderdale.

And let's go back to the springtime of 1986.

Dearfellabeech is also the home of Darrell Adams, who is a true family man.

He grew up with six brothers and sisters.

And when I talked to Darrell, one sister in particular, he felt the closest to.

Angela was the best sister you could ever wish for.

She was very protective, especially of me.

I was the youngest of seven kids.

She would get out and she would play football with this.

And if I got shoved around a little bit too much, you would be the first one to jump in and take my side.

And you know, don't shove my little brother around.

And he just couldn't ask for a better sister.
