The girl is suspected of fatally shooting two teenage boys, one in Rosengård in Malmö and the other in Vårby outside Stockholm.
According to prosecutor Anna Asklöf, the girl contested her detention in both cases. Asklöf declined to say whether the suspicions had been strengthened or weakened.
The investigation is ongoing, and there is a risk it will be affected if she is released or if she continues to commit crimes," Asklöf tells TT.
The girl is suspected of carrying out the shooting in Rosengård along with a 17-year-old boy. He has confessed to the crime and agreed to be held in custody.
A 35-year-old man and a 30-year-old woman are also in custody for aiding and abetting the murder.
