Thirteen-year-old Lisa T. from Berlin, whose body was found in Brandenburg, was apparently the random victim of a 22-year-old paedophile. “So far, the investigation has found no evidence of any prior relationship between the victim and the suspect,” the Berlin Public Prosecutor’s Office said on Monday.
The suspect, who was found with serious injuries, had previously been investigated several times on suspicion of “acquiring and possessing child sexual abuse material”.
Lisa T.’s body and the suspect were discovered on Sunday in an unoccupied detached house in a district of Bad Freienwalde, Brandenburg. He is believed to have inflicted his injuries on himself. Investigators confirmed on Monday that the 22-year-old suspect had been conclusively identified. He is a German national from Berlin.
Forensic examinations also conclusively established that the deceased girl was Lisa T. A post-mortem examination has not yet determined a clear cause of death. Further tests have been commissioned. According to the Public Prosecutor’s Office, there is no evidence of any accomplices.
According to investigators, proceedings against the suspect, who had no previous criminal convictions, had been ongoing in Berlin since January 2025. The investigation concerned more than 900 files containing suspected child sexual abuse material that had been seized during a search. He is believed to have obtained these files in 2023.
A second investigation, transferred from Passau, concerned “a large number of additional suspected child sexual abuse materials” found on the man’s mobile phone. He had spent some time in Bavaria.
Lisa T. had been missing since Tuesday morning. She left home to travel to school but never arrived. On Friday, police announced that the 13-year-old had most likely “not left her home environment voluntarily”. On Saturday, authorities stated that they had to “assume that a criminal offence had been committed”. Police then released a photograph of the missing schoolgirl and appealed to potential witnesses to contact the Berlin State Criminal Police Office (LKA).
The suspect was still receiving intensive medical treatment on Monday. Possible evidence was seized from his apartment in Berlin’s Marzahn-Hellersdorf district. Police also continued their investigation at the scene in Bad Freienwalde.
