(CNN) — All Terry Pettit could do outside the offices of the Inland Regional Center in San Bernardino, California, was worry.
News of shootings at the agency for people with developmental disabilities were spreading fast — with possibly 20 victims — and all Pettit knew about his daughter inside the building were the text messages coming to his cell phone.
“Shooting at my work. People shot.”
“Pray for us. I am locked in an office.”
Pettit cried as he spoke to reporters. Sirens blared in the background.
“She’s been hiding,” he said.

Details of yet another mass shooting were trickling out.
Witnesses told police they saw three men with long rifles, a law enforcement source said. The three men got into a black SUV and drove away, the source said, citing the witnesses.
After a SWAT team cleared the building where the shooting occurred, a sheriff’s bomb squad found a suspicious package on the second floor, the source said. An explosive ordnance disposal team determined it is “not normal” and they are going to handle it by robot, the source said.
Marcos Aguilera told CNN affiliate KABC-TV that his wife had just made it out of the building.
“She said the guy came in next to her office and I guess started shooting,” he said. “Then he locked himself in her office. They’ve seen bodies on the floor. She said right now ambulances are taking people out in stretchers.”
Inland Regional Center’s Facebook page says it employs nearly 670 staff at its facilities in San Bernardino and Riverside counties, providing service to more than 30,200 people.
The center aims to “work on a personal, one-on-one basis with people with developmental disabilities to make their lives better as they define it.”
On Wednesday afternoon, however, the area surrounding the center resembled a war zone, with dozens of people walking out of the building with their hands in the air and lines of heavily armed officers aiming their weapons. Some of the wounded were taken out on stretchers. Triage stations were set up outside.
It is unclear how many people were at the San Bernardino facility at the time of the shooting.
Kristin Krause, who works at a charter school about a mile away, said the staff and 400 students were on lockdown.
The students were secure, she said.
“We have all gates locked. We are doing everything we can to make sure our kids are protected.”
A facility for the blind that caters to mostly elderly people across the street from the shooting scene also was on lockdown, according to Elizabeth Mendieta, a driver who transports clients.
