The shooter was later identified as 29-year-old Gavin Eugene Long, a former Marine who served 5 years in the military, including a tour of duty in Iraq. Last year, Long filed paperwork claiming to be a sovereign citizen. A prolific poster on social media, he assumed an extremist persona online and became increasingly outspoken after the controversial shooting death of Alton Sterling in Baton Rouge. 

Long was shot and killed, ending the bloody standoff, but not before killing three law enforcement officers, including Baton Rouge Police officers Matthew Gerald and Montrell Jackson and East Baton Rouge Sheriff's deputy Brad Garafola.

Three others were injured, including East Baton Rouge Parish Sheriff's deputy Nicholas Tullier, who is still listed in critical condition and East Baton Rouge Deputy Bruce Simmons. The third injured officer has not been identified.
