When an officer is killed in the line of duty, the FBI gathers data about circumstances pertaining to the death. The data come from various sources:
When the FBI receives notification of a line-of-duty death, the Law Enforcement Officers Killed and Assaulted program staff works with FBI field divisions to contact the fallen officer’s employing agency, requesting additional details about the fatal incident and supplying information about federal programs that provide benefits to survivors of law enforcement officers killed in the line of duty. The staff also obtains criminal history data from the FBI’s Interstate Identification Index about people who are identified in connection with line-of-duty deaths.
