Police Outline Baton Rouge Gunman's Actions

Authorities today outlined how they believe the gunman who shot and killed three law enforcement officers in Baton Rouge carried out what Louisiana State Police Superintendent Col. Mike Edmonson called a "calculated act."

The gunman, 29-year-old Gavin Long, a former U.S. Marine, "dismissed" civilians and "intentionally targeted and assassinated" cops, Edmonson said.

The Sunday shooting left three officers dead and three other officers wounded. Police shot and killed Long.

"Our hearts are broken but our spirit is intact," Edmonson said.

Gov. John Bel Edwards said Long, who was from Kansas City, Missouri, came to Baton Rouge "to do harm to our community" and specifically harm law enforcement officers, calling it a "diabolical attack."

Edwards said the "heroic" officers "ran towards danger in order to protect the public" and render aid to fellow officers.

Edwards said that for six days prior to Sunday's attack there had been no arrests in Baton Rouge related to Alton Sterling protests.
