What is it with criminal type people? They all think what how smart they are. Most criminals get caught because they all think out.

I figured out a way to do this and I'm not going to get caught. They're not going to catch me.

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

I'm Anna Sige-Nikolazi, former New York City homicide prosecutor and host of investigation discoveries to conviction.

And this is an anatomy of murder.

So today's story takes us to Florida, a state where I was fortunate enough to start my law enforcement career.

And covering cases there has always been pretty special to me.

When you spoke to the investigator in this case, Dan Bates, where did that take your mind about your time when you were serving down there?

So when he was talking about some of the investigative techniques and some of the things that they used back in the late 80s, it really felt pretty home to me.

Since you were down in Florida for a while, Scott, why don't you lay the landscape of Panama City out of it?

So clearly, Panama City is in northern Florida on the beach side. And the victim in this case is Ron Stolval.

And he was a 30 year old and vicious guy.

He was recently remarried and had a new baby, worked for UPS, but that wasn't enough for him.

He was always so ambitious he wanted to get more first family, so he's even going to masseuse school at night to really advance his career.

Ron Stolval was a young man who had his whole life in front of him.

He was trying to live that all American story we always hear about.

When this couple met, Ron was waiting tables in a restaurant and he was a single dad to a young daughter and in Galica herself was a single mom with a young son.

By 1988, they've been married about three years, but it's their routine that really gets me.

He gets up early every morning between three and three thirty every morning.

He goes out to the UPS, his worry works, and she gets up every morning to fix his lunch.

Now that's dedication. I mean, for me, I'm not getting up three thirty in the morning for too many things.

Work is probably about one of the only things I would do that for otherwise. I'm not getting up, but for her, she chose to get up every single morning, really in the middle of the night, to make him his lunch.
