Behind a chain-link fence and under heavy security, workers returned to their offices at the San Bernardino campus where 14 people died last month in a massacre.
Inland Regional Center employees flashed their identification badges to security guards who ushered them into a parking lot surrounded by a mesh-wrapped fence as dozens of news reporters stood outside.
Since the attack, few employees of the center that serves autistic children and mentally disabled adults have gone to the office, other than for brief visits to gather personal belongings.
Melvin Anderson, who helps transport the center's clients, was trying to figure out where he could turn in paperwork to get paid. The last time he did that as he does each month - was the day before the December 2 terror attack at a holiday luncheon for county employees. The gathering was held in a building on the gleaming campus.
"It's scary, really scary, but we as Americans just have to face what's going on and try to move on," Anderson said. "We've got to pull ourselves together, and we've got to go on."
Many of the center's roughly 600 employees have continued to work and visited their clients' homes over the past month. But they hadn't been together in the place where everything froze since law enforcement officers whisked them away after the gunfire.
Amid the investigation and cleanup, the campus has been locked behind the temporary fence. Within that perimeter, in one corner, is a second fence. It seals the conference center that San Bernardino County's health department was renting for the holiday luncheon when the two shooters began their assault.
A county restaurant inspector targeting his co-workers was joined by his wife in killing 14 and injuring dozens in the attack. They were motivated by radical Islamist beliefs, according to the FBI.
The conference building did not reopen Monday, and it's unclear when it might.
In the afternoon, more than 3,000 people attended a memorial service for victims of the shooting organized so county employees could mourn together.
Those gathered at the arena in Ontario heard consolation and inspiration from speakers that included former New York Mayor Rudy Giuliani and evangelical pastor Rick Warren.
Both pulled from their own experiences dealing with loss Warren's following the death of his son and Giuliani from his time at the helm of the city during the Sept 11, 2001, terror attacks and urged the audience to make something good come from this tragedy.
