The perpetrator, Samuel Straško was an 18-year-old student of the high school in Spišská Stará Ves, who resided in the nearby village of
Ľubica. As a student, he excelled academically and athletically, having successfully participated in mathematics and German language competitions as well as various sports tournaments. At the same time, he had a long history of verbal and physical attacks against female classmates and was previously expelled from high schools in
Lučenec and
Kežmarok for repeated violent incidencts. The most severe incident happened in late 2021, when Staško attacked a female classmate with his fists; her injuries required medical attention. In February 2022, he received a suspended sentence of four months in prison. He was also sentenced for threatening another female classmate with death, but not given any additional sentence because the judge considered the suspended sentence issued in the other case sufficient. In Spišská Stará Ves, the pattern of violent behavior continued. Straško was removed from an online classroom during the
COVID-19 pandemic for sending death threats to a female classmate. He later attacked the classmate by crashing his bike into her on purpose and threatened another female student with murder on a school trip. Due to his violent behavior, the school assigned Straško to an individual study plan, where he studied at home and attended regular exams at the school. According to his fellow students and teachers, Straško was an intelligent but troubled student. In addition to repeated outbursts of aggression towards other students, particularly female ones, he was known for speaking German and performing the
Hitler salute during school breaks. He repeatedly expressed hatred towards
Romani people and women. He also actively sought sadistic content online. ==Investigation==
