The Honeytrap Failure and the Hunt for the Wimbledon Common Killer
The murder of Rachel Nickell in front of her two-year-old son, Alex, triggered immense public pressure on the Metropolitan Police. Desperate for a breakthrough, detectives focused their attention on Colin Stagg, a local man who frequented the common. Lacking any physical evidence linking him to the crime, police launched Operation Edzell, employing an undercover female officer to elicit a confession through a romantic ruse.
This highly controversial "honeytrap" operation backfired spectacularly. In 1994, Mr Justice Ognall threw the case out of court at the Old Bailey, condemning the police tactics as an attempt to "warm up a suspect." The real killer, Robert Napper, remained at large for years, committing further violent crimes before DNA advances finally linked him to the Nickell murder scene. Napper eventually pleaded guilty to manslaughter on the grounds of diminished responsibility in 2008.
