SAN BERNARDINO, Calif. (AP) – San Bernardino County leaders are vowing increased security at county facilities Monday as thousands of employees return to work after a restaurant inspector and his wife opened fire on a gathering of his co-workers, killing 14 people and wounding 21.

During a press conference Monday, leaders said there will be more security guards at the facilities and they will now be armed. The San Bernardino County Sheriff’s Department will also increase patrols at county buildings.

Also speaking at Monday’s news conference was County Public Health Director Trudy Raymundo and Department of Environmental Health Services Division Chief Corwin Porter, who were among those who attended the holiday party that was attacked. Raymundo said San Bernardino County will heal and rebuild and will come through stronger on the other side.
