That guy seems to have been pretty stupid, to be frank. Used the same postbox for all letters, and didn't put enough stamps on some packages. I don't think this in any way suggests somebody with basic common sense couldn't be quite considerably more secure when sending things they don't want traced back to themselves. "...while the Royal Mail intercepted several other packages, which had been held up because insufficient stamps had been put on them." "After receiving the second letter, which had been damaged by fire, police made enquiries with the Royal Mail and discovered that a fire had been reported in a postbox on Bradpole Road, Bournemouth, leading to speculation that "Sally"—the alias by which all the letters were signed—had changed his mind and attempted to destroy the letter." "The police received another letter from "Sally" on 7 December. Once again, the letter was traced back to the Bradpole road postbox, where the surveillance operation had continued. The operation had captured good-quality footage of all the users of the postbox that day, but, as it was close to Christmas, the postbox was busier than normal, with 172 items posted by 38 people. Royal Mail regulations meant that detectives could not open or delay the letters, so they made enquiries with the recipients to identify the senders. They eventually managed to identify all but a small number of the senders." "On 17 February 2001—over six months after the receipt of the first demand and three months since the last letter from "Sally"—the police made a major breakthrough. Detective Constable Alan Swanton, a junior detective on the case, spotted one of the people caught by the surveillance of the postbox who had yet to be identified. The man was carrying a fuel container, which Swanton believed had come from a nearby filling station. Officers obtained CCTV footage from the filling station, where their suspect had paid by cheque, and identified the man as Robert Edward Dyer."
