On the second floor of the gleaming San Bernardino County building, cubicles are empty, boxes are stacked and a few photos and kids' art are still tacked to bulletin boards.
"Coming through here was a tough thing," says David Wert, the county's public information officer, while walking through a row of abandoned desks.
On a white board is someone's daily to-do list under the handwritten date of Dec. 2, 2015.
Employees of Environmental Health Services have not been back here since that day, when they left for a training session and holiday lunch at the nearby Inland Regional Center. Thirteen department workers died when Syed Rizwan Farook, a co-worker, and his wife, Tashfeen Malik, stormed in shooting. Another victim, not a county employee, also died. Twenty-two people were injured and many more were traumatized.

A member of the staff orchestrated the mass shooting that killed 14 and injured 22.](http://ww2.kqed.org/news/wp-content/uploads/sites/10/2016/03/SBToDoList-800x514.jpg)
In the months since, about half of the 71 people who attended the training have returned to work and more trickle back every day.
