Pin on Unsolved Murders and Mysteries

Taking place during the Pentecost of 1976 over a dark weekend in Switzerland.

The murders occurred in a protected forest in Seewen, Switzerland. Five people were found murders by a Winchester Rifle. Thirteen Rounds were fires and eleven shots hit the targets. The bullets were struck with a frightening precision. The house was named Waldeggli located in a small allotment garden.

The crime was discovered on June 6th 1976 by a female walker. When the police arrived four corpses were found in the house with a fifth carefully wrapped in a carpet on the terrace. Much speculation surrounds why a killer decided to fire 13 bullets into this mild and functional family over a quiet weekend in Switzerland.

The Murders

The murders were notable due to the precision and execution style carried out with every shot. The killer was clearly a trained marksman. However; Swiss males are required to carry out national service which means that many young men in Switzerland will be trained with rifles.

The shots nonetheless were perfectly placed with one victim having four shots taken to their head. Speculation is that the initial targets were Eugen and Elsa and the other victims caught the killer by surprise.

The police sought an Opel Car after the murder which was coloured olive green with the license plate BS28151 that according to some accounts belonged to the Siegrists. The killer apparently left the premises heading towards the Hochwald region but was stuck down in the boggy forest roads. Two blankets were found that were believed to have been used under the car wheels to get moving again.


The majority of the Swiss public believes the murderer to be Carl Doser. In 1996 the Winchester rifle was found in Doser’s home and forensic testing determined that this was indeed the murder weapon but there was not enough evidence or motive to convict Doser.

Doser was a loner that lived in Basel, some 14 miles from Seewen. Originally interviewed by the police Doser in the 70s; Doser lied about the guns whereabouts and said he sold it in a flea market. However the biggest obstacle in charging Doser was that there is no proof that Doser even met the victims in question. Doser’s current whereabouts are unknown.  

Another suspect is Johnny Siegrist, a family member to the victims he may have been in cahoots with Doser. A search by police of Johnny’s residence showed Styrofoam heads that were shot through in apparent target practice. Apparently Johnny was a short tempered man of extremely small stature that was known to Elsa and Eugen. Johnny’s height and appearance had been mocked by the couple and revenge was an apparent motive. If involved Johnny managed to escape justice by dying in the mid 1980s.

A man named Hans Blaser was an acquaintance to Siegrist and alleges that he was asked for a machine pistol by Siegrist.

Another suspect is the surviving son of Elsa and Eugen – Robert Siegrist. While in questioning for the police shortly after the murders Robert Siegrist was extremely belligerent and defensive. However there again remains flimsy evidence beyond a possible motive to link Siegrist directly for a double matricide and patricide.

With more than 40 years passing since the murder – justice will never be found in this matter as the statute of limitations in Switzerland has now passed and there will no longer be any investigations carried out.
