Dr. Adam Vaughn is a low-rate transplant surgeon responsible for stealing organs, bones, and grafts from donors who didn't actually consent to the donations. Vaughn found the victims through Tony Bicks's funeral home, which cremated them to hide the evidence, while nurse Valerie Miller would forge the records to hide the crimes.
Vaughn took transplants from a woman with ovarian cancer, which killed Michael Jones and endangered the life of Jason Carter. He was acquitted at his trial for murder. (L&O: "Remains of the Day")
