German authorities have confirmed that the body found in Brandenburg is that of Lisa, who had been missing since Tuesday, 3 November.
The discovery was made in an empty building near the Polish border, more than 50km from the girl's home.
In addition to the body, police also found a seriously injured unidentified man at the location. According to authorities, the suspect is believed to have wounded himself before being transported to hospital, where he remains in a critical condition, as reported by Bild.
Lisa disappeared after leaving her home at around 7.15am to go to school. She never arrived at her destination, prompting a large-scale search by investigators since Friday.
Authorities believe she did not leave her familiar environment voluntarily.
The public prosecutor's office has stated that a serious crime is suspected. The exact circumstances of Lisa's death remain unclear as the investigation continues.
