A 17-year-old is suspected of having killed his sister and seriously injured his mother in Middle Franconia. An arrest warrant was issued against him on Saturday, said a police spokesman.

On Friday, the police found the body of a 14-year-old teenager in a house in Weisendorf near Erlangen. They discovered the seriously injured mother outside the house. The police arrested the 17-year-old shortly thereafter “near the scene of the crime”.

According to the first impression, the 14-year-old died from a pointed, sharp object, probably a knife, as the spokesman said. The mother was taken to the hospital with serious injuries, but her life was not in danger. There were traces of blood on the house next door. They may come from the woman. It must now be evaluated who the blood came from and how it should be classified in connection with the crime, said the spokesman.

According to initial findings by the police, the woman and the two young people were alone in the house at the time of the crime. The police did not provide any information about the father of the children. The Kripo Erlangen has taken over the investigation.

What exactly happened in the house, whether there was a loud argument, whether the mother or daughter was attacked first, whether the son wanted to flee or was willing to be arrested – that initially remained in the dark, as did a possible motive.

Weisendorf has just 6800 inhabitants. Candles and flowers were left at the crime scene on Saturday.
