CHATTANOOGA, Tenn. – The FBI has not ruled-out, any possible motive for the attacks at a Navy-Marine training center and a military recruiting center in Chattanooga.
Four Marines were killed along with the lone gunman, 24-year-old Muhammad Youssef Abdulazeez.
It’s not known if he was killed by officers during a firefight or if he took his own life.
He is from Hixson, Tennessee, which is just a few miles across the river from Chattanooga.
Two of the four Marines killed have been identified.
The India Battery 3rd Battalion 12th Marines posted on their official Facebook page that Thomas Sullivan, a western Massachusetts native, was killed in a suspected home-grown terror attack. ABC News has also confirmed that Sullivan grew up in Springfield.
The second Marine has been identified as Skip Wells, according to CNN. Wells graduated from Marietta, Georgia Sprayberry High School in 2012.
“We are treating this as an act of domestic terrorism,” said Bill Killian, a U.S. Attorney for the Eastern District of Tennessee.
Witnesses and local media reports said the gunman, driving an open-top Ford Mustang, fired at two locations including a military recruiting center and a U.S. Navy Reserve center about six miles apart. Witnesses said they heard scores of shots.
The names of those killed and wounded have not been released.
The city police department said that the “active shooter situation” was over a couple of hours after the incident began around 10:45 a.m.
“We’ve got an officer down,” Chattanooga Mayor Andy Berke told reporters, calling it a “very terrible situation.”
An active duty Army recruiter in Chattanooga says he was at his office when someone opened fire and he heard 30 to 50 shots.
Sgt. 1st Class Robert Dodge, 36, was working at the Armed Forces Career Center off Lee Highway. There are also offices for Air Force, Navy and Marine Corp there.
“We heard one single shot, which kind of sparked our attention. Shortly after that, just a few seconds, the shooter began shooting more rounds. We realized it was an actual shooting, so we then initiated our active shooter drill: getting down low to the ground, moving to a safe location. And we waited until everything seemed to be clear.”
He said he did not see the shooter or a vehicle.
