The suspect has been identified as a black male named Gavin Eugene Long of Kansas City, Missouri, sources tell CBS News. He was born on July 17, 1987…

A witness tells CBS affiliate WAFB that he saw a masked man in black shorts and shirt running from the scene where three Baton Rouge law enforcement officers were shot and killed.

Brady Vancel said the man looked like a pedestrian running with a rifle in his hand, rather than someone trained to move with a rifle.

Vancel said he’d gone to work on a flooring job on a street behind the gas station where authorities say the shooting occurred. He said he heard semi-automatic fire and perhaps a handgun.
