Polish authorities investigate potential record-breaking serial killer

A 43-year-old plumber identified as Michael P. is currently facing charges in Poland for the murder of at least seven women. Investigators suspect he may be the deadliest serial killer in the country's history, noting that the death toll could be significantly higher as authorities analyze 75,000 photographs discovered on the suspect's mobile device. Two Ukrainian nationals have also been arrested as accomplices to the crimes.

Working as a plumber, the suspect utilized his professional access to scout the homes of vulnerable women. He would return later to subdue, threaten, and kill his victims after forcing them to disclose the location of their valuables. Michael P. was apprehended in February 2025 after a bank customer service employee overheard him strangling a victim who was on the line attempting to reset her card PIN. The suspect was found beneath the victim's balcony when police arrived at the scene. Investigations are ongoing to determine the full extent of the suspect's criminal activity.
