This consisted of compiling 483 known supposed characteristic of the Vampire, both physical and mental, which were then compared with those of the thousands of male residents of the Dąbrowa Basin. Following this, 267 potential suspects remained, and in fourth place was Zdzisław Marchwicki. For various reasons, the other top three suspects were later eliminated, and more attention was paid to Marchwicki, but authorities could not yet arrest him, as there was no direct evidence in his guilt.

How many of you are here - no more, no less, as the Vampire himself has been grabbed"; in the court files, he is recorded as saying "Well, now, finally, the Vampire has been caught." Almost immediately after his arrest, the task force was split in two groups: those who believed that Marchwicki was guilty (chief among them
