Story highlights Two die in murder-suicide, Bexar County Sheriff's Office spokesman says

Source: Airman shot his squadron commander

No arrests reported; shooting was not a terrorism situation, brigadier general says

(CNN) Two people are dead after a shooting Friday morning at Joint Base San Antonio-Lackland -- an incident that involved an airman shooting his squadron commander, a Pentagon official told CNN on condition of anonymity.

James Keith, spokesman for the Bexar County Sheriff's Office, said it was a murder-suicide.

No arrests have been reported, but the situation is over and a lockdown at the Texas facility -- also known as Lackland Air Force Base -- has been lifted, Brig. Gen. Robert LaBrutta told reporters.

LaBrutta gave few details about the shooting, which was reported at 8:40 a.m. (9:40 a.m. ET) in Forbes Hall, a building with offices and classrooms. He declined to identify the dead and gave no details about any relationship between the two, what led to the gunfire, or what ended it.
