The latest on the reopening of the social service center where 14 died in the San Bernardino shooting (all times local):

8 a.m.

Guards checked IDs as workers returned to the San Bernardino social service center for the first time since 14 people were killed last month in a terror attack.

A chain-link fence was unlocked Monday morning as some of the Inland Regional Center's 600 employees went back to work. Few of them have gone to the office since the killings, other than a brief visit to gather personal belongings. No visitors are allowed.

While many have continued to work, visiting the homes of autistic children and mentally disabled adults, they haven't been together since law enforcement officers whisked them away Dec. 2.

The conference center where the two attackers opened fire on a holiday luncheon will not reopen Monday, and it's not clear when it might.
