Last wounded victim in naval air base attack leaves hospital

The last person wounded in the deadly attack at the Pensacola Naval Air Station has been released from the hospital. The Pensacola News Journal reported Saturday that the unidentified victim has been discharged. Federal authorities say Saudi Air Force 2nd Lt. Mohammed Alshamrani killed three U.S. sailors and injured eight other people at the naval station on Dec. 6.

Investigators are digging into whether he acted alone, amid reports he hosted a party earlier last week where he and others watched videos of mass shootings. Security at the base has been tight and is only open to those with a current Department of Defense ID card.
