Mr. Rawley (first name unknown) is the father of comatose car crash victim Stephanie Rawley. He was horrified to find out his daughter was raped and impregnated in her vegetative state. He always blamed her fiancé David Anderson for the accident and suspected him, but he was cleared.
He was coaxed to terminate the pregnancy by Dr. Graham Mandell, Stephanie's neurologist, and it was nearly performed by Dr. Garrison. When the detectives found out, Stabler carefully asked for a DNA sample to eliminate him as a suspect, leading Mr. Rawley to punch Stabler. Benson was ready to arrest him for assaulting an officer of the law, but he gave his sample, which didn't match, and revealed Mandell as the doctor responsible for the order.
Mandell and Garrison had inseminated Stephanie to use her stem cells to treat Parkinson's, which was paid for by afflicted billionaire Davis Langley. Mr. Rawley testified at the doctors' trial, speaking about his daughter's life, her accident, and the betrayed trust their family put in the doctors. It wasn't enough to prevent the doctors from getting acquitted with minor penalties and Langley sue for the grandchild to get the baby's umbilical cord. (SVU: "Waste")
