The men had been in a federal lawsuit over the ownership of the image of Lockhart, who works as a pornographic actor and model under the stage name Brent Corrigan. A settlement to the federal suit was to be mailed to Kocis the day after he was found dead, Yates said.
Yates said he understands police want to question his clients about the mystery man said to have been scheduled to model for Kocis, a pornography producer, the day he was killed.
Prosecutors were granted a search warrant Friday to review Kocis telephone and Internet records.
They hope to learn Kocis associates and activities in the week prior to his murder because investigators believe he may have been in contact with his attacker or attackers.
An affidavit of probable cause filed with an application for the warrant stated a folding-style knife was found near the victims body, which was burnt beyond recognition, forcing medical examiners to identify Kocis from dental records.
Luzerne County Coroner Dr. Jack Consalvo determined Kocis died some time before the fire started, but Consalvo could not determine exactly when because of the bodys condition. The blaze also prevented Consalvo from determining whether the knife at the crime scene was the murder weapon.
It was capable of producing those wounds, he said, but to say definitely it was the weapon, youd need to get DNA off the knife, which is unlikely because of the fire.
The affidavit states the fire originated near the living room couch where investigators discovered Kocis body stabbed in the torso and slashed across the throat. According to the affidavit, police saw no sign of struggle or forced entry. No accelerants were used to fuel the fire, Consalvo said Tuesday.
The Web site for Kocis pornography business, Cobra Video, was operating as of Tuesday night after appearing to have been taken down Monday night.
