with
Eastbourne beyond|alt=Photograph of scrubland on Beach Head A new suspect emerged in the late 2000s,
serial killer and sex offender
Peter Tobin. Tobin had killed 23-year-old Angelika Kluk in Glasgow in 2006, but was subsequently linked to two missing persons cases from 1991 after police suspected he was responsible for numerous other murders. Police set up Operation Anagram after his 2006 murder, with the aim of tracing Tobin's past movements and investigating whether he could be linked to unsolved murders. Earl was known to have been nervous about a man she had met while previously out walking, and had reportedly described meeting a middle-aged Scottish man near the same spot her body was found. In the 2022 inquest into her death it was discovered that one of her last conversations with her mother had been about meeting this man on Beachy Head, when she also commented "I wish men would be prepared to be just friends." Shortly after the discovery of Earl's body became public knowledge in 1989, Tobin hurriedly moved with his wife and child a great distance to
Bathgate,
Scotland, without prior informing his wife of these plans, which suggested he had an underlying reason to suddenly leave the area. This was notably similar to how Tobin had suddenly moved a long way from Bathgate to
Margate in 1991, shortly after he had murdered 15-year-old Vicky Hamilton in Bathgate, which showed that he had a habit of moving across the country to avoid being detected for crimes he had committed. This was further suggested to be the case in Earl's murder as Tobin was found to have checked into a hospital in Glasgow a few days after she was killed, which again fitted his habit of moving as far away as possible after committing a murder. When Earl was found, her bra had also been used to tie her hands, and Tobin was known to have tied Vicky Hamilton's hands with her bra when he murdered her. In
Mark Williams-Thomas's book
Hunting Killers, he stated that although Tobin buried his known murder victims, he also carried out merely opportunistic crimes like Earl's case appeared to be. In 1994 he trapped two neighbouring 14-year-old girls in his flat before turning on the gas taps and leaving them for dead, indicating he carried out disorganised, random attacks and could have done so on Earl as he walked past her on Beachy Head. As part of Operation Anagram, police took
DNA samples from Earl's parents and from her clothing, hoping to find a match with Tobin's clothes or possessions. However, police were unable to find enough evidence to charge Tobin with Earl's murder. A DNA link between Tobin and Earl's body could not be established through modern forensic techniques due to the key forensic evidence being destroyed by police in 1997.
Louise Kay links Apparently linked to Earl's murder and a similar case Operation Anagram investigated was the disappearance of 18-year-old Louise Kay from the same town of Eastbourne in 1988, a case which bore notable similarities to Earl's murder. Not only had both young women last been seen in Eastbourne, but Kay's last known location was also at Beachy Head, where Earl's remains would be found only a year later. Kay had been out with friends the evening she disappeared and ended the night by dropping her friend off by car at her house in Eastbourne, saying she was going to spend the night sleeping in her car on Beachy Head as she often did. Kay has never been found. As with Earl, Operation Anagram established that Tobin was also living in the area at the time of Kay's disappearance, and it was discovered that he was working in a hotel in Eastbourne. Kay's distinctive
Ford Fiesta, which was gold with a white door, that she was driving that night disappeared with her and has never been found, and Anagram established that Tobin was selling a small hand-painted car after Kay's disappearance. Kay had also met an unknown Scottish man in Eastbourne a few days before she vanished, who had given her money to buy petrol. Some of Tobin's former homes in
Brighton were searched in 2010 in the belief that Kay may have been buried there, although she was not found. In 2018, investigative reporter
Mark Williams-Thomas released a documentary as part of his
The Investigator: A British Crime Story series, in which he asserted that the cases of Earl and Kay were likely linked and that both women were victims of Tobin. In criminologist
David Wilson's 2012 episode of
Killers Behind Bars: The Untold Story that centred on Tobin's involvement in Earl's murder, Kay was also briefly brought up. Operation Anagram's lead officer, Detective Superintendent David Swindle, told Williams-Thomas in the 2018
The Investigator documentary that he believes Tobin murdered Kay. ==Subsequent developments==
