Mastromarino, a former oral surgeon, paid funeral directors $1,000 per corpse, then sold the parts to tissue banks, Sagel said.
The body parts fetched up to $10,000 apiece, though tissue banks resold them to hospitals for many times that amount, he said. Mastromarino is believed to have taken in $6 million to $12 million since 2001.
The body parts were used in disk replacements, knee operations and dental implants performed by unsuspecting doctors across US and Canada.
