She had celebrated with hundreds of other guests in a club - hours later she was dead: a young woman from the Upper Bavarian district of Rosenheim was the victim of a violent crime.

The 23-year-old from Aschau in Chiemgau visited a local music club on Sunday evening and then died violently, the police headquarters in Upper Bavaria South reported on Tuesday.

Forensic doctors had found clear traces in their investigations that suggested external violence and thus proved a homicide.

The police did not provide details for investigative reasons.

The “Club” special commission was set up at the Rosenheim Criminal Police Inspectorate.

Around 40 investigators are conducting the investigations under the direction of the public prosecutor's office.

The woman left the club called Eiskeller around 2:30 a.m. early Monday morning.

"We have already been able to reconstruct that," said police spokesman Stefan Sonntag.

A passer-by discovered the woman's body around 2:30 p.m. downstream in the Prien and informed the authorities.

The site of discovery in the Kaltenbach district of Prien is about ten kilometers from the club in Aschau.

"Where she died, how she died, and above all by whom she died - these are the questions that we now have to clarify," Sunday continued.

"We are at the very beginning." Several of the woman's acquaintances also visited the club.

They are now also relying on observations by club guests.

"We are currently looking for witnesses who may have seen: Did she go in this or that direction?" According to the police, an open question is whether the 23-year-old was accompanied.

Several people have already been heard.

But there are many more hearings to come.

Several hundred people celebrated in the club that evening.

On Tuesday afternoon, a large number of police were looking for traces in the area around Aschau im Chiemgau.

Among other things, the woman's black shoulder bag and black leather jacket were still missing.

More than 100 police officers were on duty.

According to the information, service dogs were also involved at times.
