RCMP can confirm that laboratory results were recently received on the Strathcona County explosion investigation which occurred in November 2018.
Traces of nitrate salts and aluminum powder were located on the post blast debris sent for testing, however, due to fire suppression efforts the samples were degraded to the point that direct identification of the substance could not be made.
Nitrate salts and aluminum powder can be found in a number of products including binary explosive, or "target shot", such as Tannerite. Based on the lab results and further investigation into Kane Kosolowsky's familiarity with the substance and method of ignition, the RCMP believe it is likely Tannerite was the explosive used.
The Alberta RCMP Behavioural Sciences Group, Threat Assessment Unit, has been engaged to review the evidence in this case to help provide an understanding of Kane's behaviours and any possible motivation leading up to his death. As previously released, there has been no evidence linking this incident to any terrorist group or threat. The evidence, including video surveillance and background investigation, indicates that Kane Kosolowsky acted alone.
"While there are questions that are unanswered, and the investigation will remain open, this is the final piece of substantive information that we will have to offer the public," said Superintendent Dave Kalist. "I would personally like to thank the Strathcona County officials, and the Kosolowsky family for their continued cooperation."
The family continues to ask for privacy at this time.
