Details continue to emerge about the attack on the two military facilities in Chattanooga on July 16, 2015, and we continue to get a better picture of what actually happened that day. Here are a few questions that keep coming up.
Was ISIS involved?
U.S. officials are still investigating the possibility, but they have made it clear that at this point, they believe that Abdulazeez acted alone. In other words, they do not believe that anyone — ISIS or otherwise — helped him carry out the attacks.
However, the FBI has found evidence that Abdulazeez read materials online from Islamic extremists. Officials have also found that he researched martyrdom and followed an al Qaeda radical online.
How long did the gunfire last?
The shooting at Lee Highway lasted for about a minute, witnesses said. The shooting at the reserve on Amnicola Highway lasted between three and five minutes, according to the FBI. The FBI's estimate of how long the gunfire lasted is a much shorter time than some witnesses originally reported.
The first shots fired call from the armed forces recruiting center on Lee Highway came in at 10:51 a.m. Abdulazeez then drove to the U.S. Naval and Reserve Marine Center on Amnicola Highway and opened fire. Police received a shots fired call from the reserve center at 10:58 a.m., and the shooter was killed shortly after police arrived. An exact time of death has not been released, although witnesses say they stopped hearing shots around 11:04 a.m.

Will military recruiters in the U.S. be armed now?
In Tennessee, all seven of National Guard storefront recruiting offices have been temporarily relocated to armories. The state is also now accelerating handgun-carry permit applications for Guard members.
However, while the National Guard reports to the governor, the rest of the state's military facilities are under the control of the Pentagon, which has rejected calls to arm all service members at U.S. bases.
Rep. Scott DesJarlais, along with the entire Tennessee delegation, has introduced the "Enhancing Safety at Military Installations Act" in Congress. The bill would repeal bans that prohibit military personnel from carrying their firearms at military recruitment facilities and bases.
Who was wounded?
Chattanooga police officer Dennis Pedigo, who was shot in the ankle, is in stable condition at Erlanger Hospital. Marine recruiter Sgt. DeMonte Cheeley was treated and has since been released.
