In August 2005, Alex Kravchenko was hired as an investigator of the Special Investigations Unit, Ministry of the Attorney General of Ontario. He investigated multiple high-profile, sensitive cases, such as firearms deaths, custody injuries, and allegations of sexual assaults involving police officers.
