SAN ANTONIO --The fatal shooting of two people at an Air Force base in Texas appears to be a murder-suicide, authorities said Friday.

Two bodies were found inside a room of a building at Joint Base San Antonio-Lackland, Bexar County sheriff's spokesman James Keith said.

It's believed the shooter is among the two dead, Keith said, adding that sheriff's deputies and other law enforcement officers are continuing to search the building and nearby facilities.
