Authorities have called off the search for a missing woman who failed to return from a planned hike on Mt. Tamalpais in Marin County.
About 100 people in all had been looking for 25-year-old Veronica Ruiz since she was reported missing Monday night.
Ruiz is an Internal Revenue Service agent.
A co-worker says Ruiz recently became despondent over a breakup with her boyfriend.
Agents searched the Mill Valley apartment where the couple lived and recovered the keys to her department vehicle.
They did not find her handgun, which she was authorized to carry as part of her job.
