In November 1990, Shawcross was tried for the 10 murders in Monroe County. The trial was televised and drew high ratings. Shawcross pleaded not guilty by reason of insanity, but the jury found him sane and guilty. The judge sentenced him to 250 years’ imprisonment.
A few months later, Arthur Shawcross was taken to Wayne County to be tried for Gibson’s murder. Rather than claim insanity this time, he just pleaded guilty and was given a life sentence.
In 1992, true crime author Joel Norris wrote a book about the case. The paperback came with a tape that contained “the live confessions of Arthur Shawcross and his hideous crimes!” This drew some criticism that Norris was sensationalizing the case.
In 2003 he was interviewed by a British reporter, Katherine English, for a documentary on cannibalism. The convicted serial killer bragged about slicing out and eating the vaginas of three victims, but refused to discuss allegations of eating the genitals of the boy he killed in 1972. Some criminologists have doubted these stories and suggested Shawcross embellished his crimes to impress the reporter and viewers. He died in 2008.
