That's all he said.

But there is no hard evidence Dennis had actually told his son that he was cutting him off.

But Leroy also says what the defense and Eric have claimed from the beginning.

Father and son were close.

The defense says given that tight family bond, it would have been impossible for Eric to kill his parents and conduct himself normally just hours later.

Close friend Joe Breyer met Eric and Christine for drinks the night of the murders.

If Eric had just come from his parents' house, would he have been able to present himself like that to you, do you believe?

The defense resurrects a theory investigators had rejected, that Dennis and Myrna were mistakenly murdered by a hired gunman who went to the wrong address.

Would you tell us your full name for the records, please?

Steven Robert Burgess.

Steve Burgess is the banker who lived just two houses from the Colas.

He's the one who had received death threats.

Did you receive threats such as your time is limited?

Yes, I did.

Did you receive threats that your days are numbered?

Yes.

We don't know who killed Dennis and Myrna Cola.

What we know is that the crime scene

certainly suggests somebody who was well-planned, who knew what they were doing.

Viewing the forensic data sources... Bolstering their hitman theory, the defense then calls forensic expert Max Scott.
