According to Jedynka, a 28-year-old Pole admitted during interrogation that he had received an order for the murder.

According to investigators, the suspect transferred 100 thousand zlotys (about $ 26 thousand) to an accomplice who was supposed to eliminate the politicians.

In January 2019, an attack was made on the mayor of Gdansk, Pavel Adamovich. The politician was hospitalized with stab wounds in a hospital, where he later died.
