CHATTANOOGA — The FBI now says a deadly shooting rampage at a Chattanooga base shooting was inspired by terrorism.
Channel 2 Action News is learning more about the July attacks on a recruitment center and Navy Reserve facility in Chattanooga, Tennessee.
The shooting left four U.S. Marines and a Navy sailor dead, including one Cherokee County servicemen.
U.S. Marine Lance Cpl. Skip Wells, 21, was among five servicemen shot and killed in Chattanooga in July.
The FBI now says it has found a motive for the shooting rampage.
"We have concluded that the Chattanooga killer was inspired by a foreign terrorists organization propaganda,” FBI Director James Comey said.
Comey said the FBI has been investigating the shootings as a terrorism case from its onset.
Shooter, Mohammad Abdulazeez did struggle with mental health issues, but police said that does not explain the deadly rampage.
He was fatally shot by police during a gun battle at the scene of the rampage.
The Department of Homeland Security is expected to announce changes to the government's terror alert system Wednesday.
Homeland Security Secretary Jeh Johnson has described the change as a new alert system, which he said would better inform the public about threats to the U.S.
This will be the third change to how the Homeland Security Department warns the public about security concerns since the Sept. 11, 2001, terrorist attacks.
The much maligned color-coded system was replaced in 2011 by the National Terrorism Advisory System, which has never been used.
The plan to change the system was announced in the wake of the mass shooting in San Bernardino, California, which the FBI has declared a terrorism investigation. Johnson said the new terror alert system will better "reflect the current environment and current realities."
