Flags are flying at half-staff across the central Texas military town of Killeen. People with strong ties to the Army are waiting to officially learn all the names of the fallen, after an army specialist is accused of killing three fellow soldiers and wounding 16 others before killing himself.
"There is no indication at this point that he was targeting specific people," said base commander Lt. Gen. Mark Milley. "But I'll await the investigation."
Base commanders are planning an official memorial next week to honor those who were killed and injured, but already they're applauding the efforts of those who called 911, confronted the shooter and helped save lives.
"There's at least one chaplain I'm aware of that shielded and saved other soldiers," added Milley. "He broke some windows, got them to safety."
On the sprawling base that sees 100,000 people each day, one main question is how can you make it safer?
U.S. Sen. John Cornyn, who visited the base today, said a full safety review of the base will be conducted. That includes the policy that allows soldiers to bring personal weapons on base.
"I'm confident that there will be a thorough review of that policy and the military will make the best judgement," said Cornyn.
