On 5 September 2012, Saad al‑Hilli, a British tourist of Iraqi birth, and his family were found shot to death near the village of Chevaline, just a short drive from Lake Annecy. The victims were all hit in the head with a pistol, a Luger P06, a Swiss army weapon from the 1950s.

For months the case had no lead. Fourteen years later, in August 2026, a tourist discovered a battered Luger P06 submerged two metres deep in Lake Annecy. The find, reported by Marianne magazine, may prove crucial now that investigators can compare the weapon to fragments recovered at the original crime scene.

French police have released the image of the pistol, which shows damage consistent with prolonged underwater exposure. They are testing it for fingerprints, DNA, and ballistic clues that could identify a suspect or establish the gun’s provenance. The firearm’s rarity—only about 60,000 were produced—makes it a potential link to collectors, or to the Swiss frontier where many Luger pistols are owned as antiques.

Alongside the weapon study, investigators are re‑examining the victims’ family dynamics, noting a family dispute over finances, a former American husband’s heart attack days before the murders, and odd comments about the cyclist who was also killed.

If the gun can be linked to a known owner, it could pinpoint motive and killer, possibly ending a decade‑long mystery that has left two children alive and a community in turmoil. The discovery offers fresh hope to a cold case that has long stumped police.
