Acting on an anonymous tip in November last year, divers hired by the tabloid ”Expressen” recovered the .357 Magnum Smith and Wesson revolver from a lake near Mockfjärd, in central Sweden, and handed it over to investigators.
The find had sparked hopes the two-decade-old mystery may finally be solved.
Police say however, they have been unable to find any DNA traces, or fingerprints on the weapon. They did not rule out asking international experts for further help to examine the revolver.
Palme was shot dead in central Stockholm in February 1986, when returning from the cinema without bodyguards. Palme’s murder, which shocked Sweden, has never been solved despite 200,000 leads over the past two decades.
