Police in Brandenburg have found the body of a missing 13-year-old girl who had been reported missing in Berlin. Prosecutors said the victim is Lisa T., who disappeared several days earlier. At the same time, investigators arrested a suspect. The man reportedly injured himself severely and is in a critical condition. Lisa T., from Berlin-Marzahn, left home on Tuesday at around 7:15 a.m. to go to school, but she never arrived. Police launched a missing-person appeal the same day, publishing her photo and asking for information from the public. The search involved about 220 officers, as well as police dogs and a police helicopter. Brandenburg police later found the body in their area, bringing the case to a new stage. The investigation is ongoing as prosecutors continue working on the circumstances of Lisa T.s disappearance.
