New York ? Indictments of the alleged leaders of a lucrative stolen body parts ring are being prepared as a Brooklyn grand jury completes its investigation, the New York Daily News has learned.

Michael Mastromarino and his one-time partner, Joseph Nicelli, 49, of Staten Island, will face hundreds of counts of fraud, forgery, filing false documents and other charges, resulting from a nine-month probe by the Brooklyn district attorney’s office, sources told The News.

Mastromarino, 44, a former dentist from Fort Lee, N.J., personally carved up many of the corpses, surgically removing bone and valuable tissue, including skin later sold in sheets, sources said.

The scheme allegedly involved paying funeral home directors and medical examiners $1,000 per corpse.

After the harvesting, corpses were generally sewn up with PVC plumbing pipe inserted where limbs had been removed, according to sources familiar with BTS procedures and exhumations conducted by the district attorney’s office.
