The event took place before midnight on Sunday, November 25, in the Český Krumlov district, instead of the police.
"The victim of a crime is a young woman and the investigator has already accused a person in this regard. Bearing in mind the fact that the case is a minor, and also in terms of survivors, we will not publish details," said South Moravian Police spokesperson Jiri Matzner.
According to unofficial information, the young man killed his half-sister.
In the South Bohemia region, only four people were killed in November. Two men were hurt in Protivin, and from Sunday, November 25, criminals are searching for and killing a man who found tourists near the Schwarzenberg Canal at Horní Peče.
