UAVs took to the skies of the Leningrad region to look for the killer - a math teacher brutally killed a two-year-old boy and left his body in the refrigerator, and also beat his partner's mother to death. He was last seen in the Gatchina district on CCTV cameras - he bought alcohol at the grocery store. Now the residents of the village of Druzhnia Gorka have been warned against search activities with UAVs so that the residents remain calm.
