The FBI is investigating the shooting at NAS Pensacola with the presumption that it was an act of terrorism, the agency said Sunday.
"We work with the presumption that this was an act of terrorism," Rachel Rojas, FBI special agent in charge, said at a news conference about Friday's attack that killed four including the shooter and injured several more.
More details that have emerged since the attack:
- The shooter, Mohammed Alshamrani — who was a member of the Saudi Air Force and was in the U.S. for military training — posted an anti-U.S. screed online before launching the attack.
- Alshamrani hosted a dinner party earlier in the week during which he and other Saudi nationals watched videos of mass shootings.
- At least one of the Saudis connected with Alshamrani videoed the attack, and two watched from a car.
- A number of Saudis have been detained since the attack.
- Alshamrani visited New York City days before the shooting; authorities are trying to piece together whether or not this was connected to the attack.
Alshamrani was an aviation student at NAS Pensacola, where members of foreign militaries are routinely trained by the U.S.
