According to a source from the Cheka-OGPU, in the middle of the evening when everything happened, the conflict was resolved diplomatically. According to eyewitnesses, one company was clearly inferior to its opponents and the young people shook hands. But in the morning, when the party ended, those who were in the minority called for reinforcements and attacked the night offenders. The fight quickly escalated into shooting – according to eyewitnesses, a native of Armenia was the first to pull out a traumatic gun (possibly a submachine gun) and shoot one of the guys (a Kumyk by nationality) while he was in his Priora. In total, three people from one company were injured, 20, 21 and 33 years old (two Kumyks and a Chechen). With gunshot wounds (traumatic pistol) of the abdomen, head, thigh and lower back, they sought medical help at the hospital. The police are looking for their attackers.
Another victim of this crazy night in Lyubertsy, in the same cafe, but in a different conflict, was a 23-year-old native of the Astrakhan region. Just a couple of hours before the massacre, he was hospitalized with an open wound to the abdomen and a gunshot wound to the groin. Unknown people attacked him, presumably because of a girl, and shot the café guest at point-blank range. The criminals also fled.
