Dennis Koula, Merna Koula: Rich Parents Murdered For Inheritance Money By Greedy Son, Eric Koula, On ID's 'The Perfect Murder'

"It makes everybody a little uneasy in the neighborhood. I talked to them many times out here when they were walking through the neighborhood. They were very, very nice people, you know, can't say anything bad about them. It makes you really, really think really watching out when you do something outside or whatever. My wife and I were talking about it, yeah, saying, talking to the neighbors it does make everybody uneasy out here, you know, there's a lot of people out here probably never thought about locking their doors before. They are now."

This was the angle that prosecutors used at trial. They painted a portrait of Eric Koula as a man who was not willing to get what he had through hard work as his parents had done. Instead, he wanted it all now and decided that his parents were going to foot the bill.

A jury found Eric Koula guilty of the double murders and sentenced him to two life sentences with no chance of parole. Today, Eric Koula is still doing his time. His appeal was denied, according to NBC-15.

The Koula case was featured on an episode of CBS 48 Hours.
