Gavin Long of Kansas City identified as Baton Rouge shooter

The police tape was removed, and traffic moved freely along the street where Gavin Eugene Long, the 29-year-old ex-Marine identified as the man who killed three police officers and wounded three others in Baton Rouge, Louisiana, lived in Kansas City, Missouri.

Investigators say Long, who was killed by police, was targeting police officers when he opened fire near a shopping center about a mile from the Baton Rouge Police headquarters. On July 5, a black man named Alton Sterling was fatally shot by Baton Rouge police outside a convenience store.

Law enforcement converged on the house on East 77th Terrace early Sunday evening. The New York Times is reporting that an unidentified man emerged from the house and was taken into custody. Before authorities arrived, reporters who knocked on the door of the house were met by an armed man who did not comment.

Long served in Iraq, attended college and is divorced. He left “a vast and angry online trail documenting his interest in black separatism and fury at police shootings of black men,” in the words of the Los Angeles Times. Long declared himself a “sovereign citizen” last year, according to The Kansas City Star.
