Saskatchewan: Mutilated bison found with anomalous chemical traces
A mutilated bison bull was discovered in Saskatchewan on March 13, 2008. Laboratory analysis later detected unusual chemical compounds in hair samples. The substance 3-hydroxyanthranilic acid suggests possible sedation prior to death.
Background
The carcass of a twelve-year-old bison bull weighing approximately 1780 pounds was found on March 13, 2008, inside a circle of melted snow. The animal exhibited classic mutilation injuries including a cored rectum and incisions near the genital region. Prior to discovery, the bull had been in excellent health with regular vaccinations.
Forensic examination of collected biological samples revealed the presence of 3-hydroxyanthranilic acid within the animal's hair. This compound represents a metabolic byproduct of tryptophan, an amino acid previously associated with sedation in other mutilation cases. Researchers could not trace the substance to environmental factors or routine agricultural treatments administered by the livestock owner.
Soil analysis from the surrounding area showed no anomalous materials, containing only standard mineral components like silicates and carbonates. The absence of tracks or evidence of mechanical extraction, combined with the unusual chemical findings, contributes to the unexplained nature of the incident.
