We already know the results of Eryk’s autopsy. Paralyzed animal was found in the Jaworzynka Valley in the Tatra National Park. Unfortunately, to shorten Eryk's suffering doctors decided to put the animal down. Eryk's autopsy was performed by the veterinary doctors of the Department of Epizootiology and Clinic of Bird and Exotic Animals, the Faculty of Veterinary Medicine, Wrocław University of Environmental and Life Sciences.

The bear post-mortem examination revealed that the cause of paralysis was very advanced inflammation, involving the vertebral bodies and intervertebral discs on the section from 2 to 4 thoracic vertebra. Nature of change (taking into account the good condition of the animal, empty digestive tract and the advancement of skin changes around the hind quarters) indicates that the exacerbation of the disease process was 3 to 5 days before finding the animal. The observed pathological changes were irreversible and lead to the total paralysis of all limbs. There was no evidence of parasites of the gastrointestinal tract, or rabies.

In addition, there is evidence of the presence of gunshot bullet in the neck muscles. It was a bullet probably from hunting weapons. Nature of change indicates that the animal was gunshot few months ago (maybe even earlier). The location of the bullet does not indicate a gunshot relationship with inflammatory swaps in the spine. Doctors conducting the section recommended further ballistic investigations.
