Best Practices for Investigating
an Officer-Involved Critical Incident

The Ohio Attorney General’s Bureau of Criminal Investigation has set the bar high nationally with its protocol for investigating officer-involved shootings. In fact, longtime BCI Special Agent Supervisor Mark Kollar recently wrote the book on the topic.

Best Practices for Investigating an Officer-Involved Critical Incident explains the investigatory process from start to finish, reinforcing the meticulous nature of these types of investigations and underscoring the importance of – and the need for – uniform standards.

Special Agent Supervisor Kollar is Ohio’s statewide coordinator for officer-involved critical incident investigations. A law enforcement officer for nearly three decades, he has investigated more than 200 of the incidents.
