Shooting In Chattanooga Leaves Four Marines Dead, Several Injured

U.S. Attorney Bill Killian originally called the situation an 'act of domestic terrorism' before deferring to federal investigators.

Four marines were killed and one recruiter was injured in a shooting on Thursday (July 16) after a gunman opened fire at a Navy and Marine Reserve Center and a Recruiting Center in Chattanooga, Tennessee, CNN reports.

CBS is reporting that police later identified the suspected shooter, who was also killed in the incident, as Muhammad Youssef Abdulazeez.

A police officer and several other people were also injured in the incident, which lasted about 20 minutes this morning at the center on Amnicola Highway, according to The New York Times. The injured recruiter was shot at the recruiting center on Lee Highway.

Although he originally called the incident an "act of domestic terrorism," according to the Times, United States attorney Bill Killian later said that the case would be handled by federal investigators, who would figure out the way the crime should be labeled.
