special summit was held in the second half of July 1965 by the provincial administration of the Ministry of Defence, which combined all the known cases into one investigation. Despite the fact that the authorities remained silent about the murders, rumors about the Vampire quickly spread, sending the local populace and that of nearby Silesia into fear. Female residents from Sosnowiec, Będzin, Dąbrowa Górnicza, Czeladź, Siemianowice Śląskie and even Katowice were afraid to go outside in the evening, prompting their husbands to escort them during the night. Another rumor claimed that the Vampire intended to kill a thousand women to commemorate Poland's millennium. Policewomen were dispatched as 'decoys' in an attempt to apprehend the killer, without any success. In 1965, a total of 11 attacks were attributed to the Zagłębie Vampire, which further hampered investigators.

Another victim, Jadwiga Sąsiek, had two high-ranking militia operatives in her family, and her brother was on duty at the police station in Będzin. In 1968, the Polish authorities finally appealed to citizens of the voivodeship to provide any information that could lead to the arrest of the Vampire, offering a reward of one million zlotys. As a result, numerous false denunciations were sent to police, both against neighbors and family members, which preoccupied the police with letters and phone calls. Each of these denunciations was carefully examined, and some even helped solve unrelated crimes. At a meeting with the head of the Homicide Division of the Ministry of Defence, Col. Jerzy Muniak and Brigadier General Jerzy Gruba proposed a new, hitherto unused method of investigation, which the task
