A former North Carolina body parts supplier accused of falsifying cadaver medical histories so he could harvest potentially tainted body tissue used in transplants has pleaded guilty to mail fraud charges.

Philip Guyett Jr. faces up to 60 years in prison and $750,000 in fines after pleading guilty Monday to three counts of mail fraud. He was freed on $25,000 secured bond and ordered to surrender his passport until sentencing, which is scheduled for June 1.

Prosecutors say Guyett received $3,000 to $7,000 for each body he harvested. They said he changed the medical histories of cadavers he used to hide evidence of disease or drug use.

Guyette now works in metal recycling. In a statement after the hearing, he apologized for any problems he may have caused.
