Vital Statistics

Circumstances of Offense:

Joy Sweatman lived in a semi-detached house on St. Andrew's Road in Coulsdon, London, England, with her two-year-old daughter Sarah; she also had a five-year-old son named Simon, but he lived with his father Gerald in Purley. Joy also rented out the upper floor of her home to a fifty-three-year-old tenant named Vernon Patton and his two children. On June 1st, 1977, Vernon returned home at around one-thirty in the afternoon and stumbled into a horrific nightmare. Joy Sweatman was lying in a pool of blood, having been repeatedly hit in the head with a hammer. After she'd fallen to the ground, her killer had stomped on her body, placing a plastic bag and a pillow over her head. The perpetrator had then proceeded to attack two-year-old Sarah, beating her head so badly that she was unconscious for four days. Sarah survived a fractured skull and identified the killer to a policewoman at the hospital in Carshalton, Surrey. One witness reported to police that he'd seen a man wearing a fawn-colored coat and a flat cap leaving the Sweatman house, wiping a hammer on his coat and appearing to have a red substance smeared on his face. This individual was then seen getting into a white Austin Maxi saloon car.

Additional Details:

A 20-man squad interviewed hundreds of local people in the hopes of catching the attacker, including all of Mrs Sweatman's known contacts and all male patients at Cane Hill Psychiatric Hospital. Mrs Sweatman's estranged husband, Gerald Sweatman, 28, who lived in Purley with the couple's five-year-old son Simon, was questioned but the case against him was promptly dropped. Forensic evidence including hair and woolen fibres were collected from the scene by detectives, but none of the samples tested provided a match. The blood proved to be Mrs Sweatman's, leaving detectives no choice but to conclude that the killer did not spill any of his own blood during what The Advertiser dubbed a "frenzied" attack. Police checked into all 3,500 owners of white Austin Maxi saloon cars in the country, but failed to find the culprit. Because there was no sign of forced entry, investigators presumed that Joy had known her killer. Her ex-husband Gerald was questioned but dismissed as a suspect, after which authorities hypothesized that the attacker was perhaps someone that Joy had met at one of the nearby clubs she liked to frequent. The child eventually recovered and went to live with her grandparents. Mrs Sweatman's adoptive parents offered a £2,000 reward to anyone with information that would lead to the killer being brought to justice. The Advertiser added £500 to this sum in the hopes that a reader would come forward and identify the killer to police. Sadly, this did not happen and the whereabouts and identity of the killer have never been found.
