Vilnius school massacre

The Vilnius school massacre was a school massacre that occurred at Joachim Lelewel high school in Vilnius, Poland on May 6, 1925. At about 11 a.m., during the final exams, at least two eighth-grade students attacked the board of examiners with revolvers and hand grenades, killing at least one teacher, several students and themselves.

Attack
Various different accounts of the incident were reported by newspapers.

A Times article stated that two students, identified as Lavrynovitch and Obrapalski, were involved in the incident. According to the article, Lavrynovitch, member of an organisation that supported Józef Piłsudski, began shooting at the teachers with a revolver after being told that he had failed exams, whereupon other students tried to disarm him. Lavrynovitch then dropped a hand grenade which killed himself and several other students. Immediately after this Obrapalski, who had also failed the tests, fired several shots at the teachers, wounding a professor and several students, before throwing a hand grenade, which failed to explode. He then committed suicide. Including the perpetrators themselves, five persons were killed, one of them a professor, and six students, as well as the headmaster were wounded.

According to an article in the Neue Freie Presse three students carried out the attack, who were identified as Stanislaus Lawrynowicz, Janusz Obrembalski and Thaddäus Domanski, who was also named Ormanski in other reports. The newspaper reported that Lawrynowicz fired several shots at principal Bieganski, after most of the students had refused to take part at the exams, while at the same time Obrembalski began shooting at the teachers. Domanski then tried to throw a bomb into the group of teachers, which slipped out of his hands and exploded at his feet, killing himself, as well as the two other attackers, and a fourth student named Zagorski. Principal Bieganski was mortally wounded in the attack and professor Jankowski, as well as seven other students were gravely injured. At least four of the wounded students succumbed to their wounds. An investigation revealed that the students had founded a communist protection organisation to counter the principals strict management of the school. The members of this organisation had met one day before the exams in a tavern to discuss their further actions.

A bomb was later found in one classroom, large enough to blow up the school building.
