The 27-year-old man was charged for the May 27 murder and for the rape of his daughter’s 13-year-old friend who was in their apartment south of Stockholm.
The man has said he doesn’t remember the crimes due to the drug high.
Police have the man’s clothes that were soaked in the girl’s blood and an emergency phone call from the friend who said the man had just killed her friend.
After the murder, prosecutors say he turned to the girl, forcing her to give him oral sex while he held a knife to her throat. After the rape, he allegedly cut the older girl in the neck and stomach.
The trial is set to start next Thursday and is expected to last three days. It will be behind closed doors since the victims are minors.
