PITTSBURGH -- A man who usually leads investigations found himself the target of one on Friday morning.

FBI agents searched Allegheny County Coroner Dr. Cyril Wecht's office. They served two search warrants and walked out with documents and computers, Channel 4's Jim Parsons reported.

One of the seized computers belongs to the county and the other belongs to the Wecht Institute at Duquesne University, Parsons reported.

Wecht's attorney, David Armstrong, said he does not know what's behind the investigation.

"I would think that it inquires into the use of county time, space, employees and whether they're on county business," Armstrong said.

Federal agents did not interview Wecht, but they did question Chief Deputy Coroner Joe Dominick, according to Armstrong.

Neither the FBI nor U.S. Attorney Mary Beth Buchanan's office is commenting on the search. Wecht also declined to speak with reporters.

"If Ms. Buchanan or whomever she designates will meet with me, I need to ask what is being investigated, because we don't know and we can't find any federal jurisdiction," Armstrong said.

In February, District Attorney Stephen Zappala launched his own investigation of Wecht, saying there is evidence that Wecht is using his public office for private gain. No charges have been filed in connection with that investigation.

In addition to his elected position as coroner, Wecht has a private consulting business as a forensic pathologist.
