Hillery was convicted for murder by a California grand jury in 1962.  Hillery was accused of stabbing fifteen-year-old girl named Marlene Miller with scissors in the small town of Hanford.  Miller was said to be sewing a dress alone in the house and did not notice an intruder sneaking into the household.  The perpetrator fought with the young woman and hogtied her and stabbed her chest.  Deputies came on to the crime scene; with evidence and a witness, all fingers pointed to Booker T. Hillery, who was on parole for rape at the time.  Hillery pleaded he was innocent, but he was indicted by a California grand jury and subsequently convicted.

This caused Booker T. Hillery to seek petitions for a retrial.

Suspect: In law enforcement jargon, a suspect is a known person accused or suspected of committing a crime.

The suspect may be a different person from the perpetrator, or there may have been no actual crime, which would mean there is no perpetrator.
