Investigação on the motivation for the shooting

Polícia Civil took responsibility for investigating the case immediately after the incident. Experts from Instituto of Criminalística collected shell casings and analyzed the bloodstains at the crime scene. The analysis of the trajectory of the shots helps to put together the puzzle of each individual’s position at the time of the shots. The testimony of Knaipp’s wife, taken in the early hours of the incident, provided the initial basis for setting up the police investigation.

The woman injured during the exchange of gunfire also received medical attention and provided formal explanations to the authorities as soon as she was discharged. The investigation seeks to detail the ownership of the weapons used and verify whether they belonged to the corporation’s official cargo or whether they were for registered personal use. Ballistics documentation is part of the process.

The professional history of the two involved showed no records of enmity or previous conflicts. The peaceful coexistence of twenty years makes the outcome an outlier in the behavior of both.

The lethal clash between two active members of Polícia Militar generates internal debates about the mental health and emotional control of the troop. The corporation has specific protocols to deal with misconduct, but the surprise factor in this case made any preventive action on the part of battalion commanders difficult. The PM’s Corregedoria monitors the progress of the investigations conducted by Polícia Civil and has initiated a parallel administrative procedure for internal archiving.

Casos of domestic violence involving security agents requires increased attention from institutions. The informal complaint made by the corporal’s wife was the trigger for the tragedy that killed the two friends. The military regulations provide for the preventive withdrawal of weapons from police officers responding to cases of family aggression. However, records indicate that there was no formal complaint against Mazeppa with women’s protection agencies before that night.

The sergeant’s death ends the phase of medical expectation for his recovery. Family members are now organizing the farewell ceremonies and burial in the capital of Paraná.
