PITTSBURGH -- The homicide trial for Bryan Sedlak continued Wednesday at the Allegheny County Courthouse, with disturbing testimony from a man who claims to have seen the defendant with Patrick Kenney on the day Kenney died.

Kenney, 22, of Jefferson Hills, disappeared on Feb. 1, 2005. His body still has not been found, although his Cadillac Escalade was recovered in Pittsburgh's Greenfield neighborhood, near Sedlak's home.

Prosecution witness Robert Hoover testified that Sedlak brought him to the former Water's Edge tanning salon in Homestead on Feb. 3, 2005, and told Hoover that he had killed someone.

Hoover said that he saw a body in the salon, and that Sedlak kicked and jumped on the person and beat him with a .22-caliber rifle as he was dying.

"I saw the body rolled up in a carpet ... he said he cut up the body and skinned it and put the skin in sulfuric acid," Hoover testified.

Hoover went on to say that he was asked to help Sedlak get rid of the body, but "I told Bryan I didn't want to have anything to do with this. I don't even want to be on this stand."

Defense attorney Lisa Middleman's cross-examination of Hoover became so heated that Judge Jeffrey Manning ordered a five-minute recess. He told the jury to leave the room, then pointed at Middleman and cautioned her that she could be held in contempt of court.

Sedlak's attorneys have said that he acted in self-defense after Kenney tried to rob him of money and drugs.

On Monday, Richard Roscoe Jr. -- a self-proclaimed dealer who was granted immunity -- told the jury that he sold cocaine to Kenney in the parking lot of the Baltimore House restaurant in Pleasant Hills on Feb. 2, 2005. He said Kenney was with a man named Bryan, although he could not say whether it was Bryan Sedlak.

Testimony resumes Friday morning.
