Transforming Practices Conference 2026

On December 05, 2005, members from the Calgary Police Service (CPS) Child Abuse Unit and Homicide Unit initiated an investigation into the suspicious death of two-year-old Blake Douglas HARVEY who died in Calgary .  The original investigative team conducted a thorough criminal investigation into the death of HARVEY but the case eventually went “cold” due to a lack of evidence against the caregiver(s).  In September 2013, the file was reviewed, re-opened, and assigned to Detective M. CAVILLA in January 2014.  

Following is a summary of the 2005 investigation as well the subsequent "cold case" investigation that followed years later (2014/2015). Collaboration between partner law enforcement agencies and medical experts will be highlighted in this case study.
