According to the boy’s attorney, the 16-year-old has admitted to intentionally carrying out the killing.

He confessed during a new interrogation on Thursday.

“He has confessed to intentional killing. That means manslaughter or murder,” Claes Borgström, the boy’s defense attorney, told Expressen.

The girl was found dead in a wooded area in Stureby in southern Stockholm after a party on the night of June 6th. She likely died due to suffocation and other external trauma, according to a preliminary autopsy report. No weapons were used.

According to Borgström, the boy was alone with the girl when she was murdered. He did not want to discuss the motivation behind the crime.

“I will remain silent on that issue. The investigation is at a point where the prosecutor has instructed us not to publically discuss the issue at this point in time,” Borgström told Sveriges Radios Ekot.

Police have previously said that it was a case of love gone wrong. A 16-year-old girl has also been detained on grounds of incitement to commit murder.
