John Whirty DOB: 2/5/1945 JRW is 68 years old now. Murder with malice (Rose Marie Martin) was committed: 3/31/1967 He started his sentence: 7/10/1967 Whirty was charged with assault on a 12 year old girl in 1966, so he fled from MA to TX. He was convicted and sentenced in 1967 to the murder of Rose Marie Martin, who was 15 years old at the time she was murdered. Whirty served 17 years and was paroled. Once paroled in 1984, he made his way back to MA. He is a suspect in the 1985 disappearances of Catherine Malcomson and Sara Pryor. He was arrested for attempted kidnapping in 1985 and shipped back to TX for a parole violation. Whirty is definitely a serial offender at a minimum, but it has to be worth looking at him for crimes in both MA and TX pre 1967 and from 1984-1985 when he was busted for the kidnapping of a Newton woman. Given the pace of his crimes when he is free, I cant believe that he didnt offend between 1984 and 1985. He is associated with Ludlow, MA and Sherborn, MA. LE states he was in the area when Cathy and Sara were kidnapped. According to the woman who was kidnapped but rescued in 1985, the interior of his vehicle was rigged to prevent escape.
