lackland air force base

A spokesman for joint base San Antonio-Lackland says military-issued and personal firearms are heavily restricted on the base and that it's not clear whether a gunman involved in a murder-suicide was authorized to have a weapon.

A Lackland Air Force instructor along with 11 other instructors face sexual assault charges in one of the largest scandals to rock the base, one of the nation's busiest military training centers located in San Antonio, Texas.
