The latest on the escape of three prisoners from a county jail in Southern California (all times local):

10:50 a.m.

California law enforcement authorities believe at least two of the three men who staged an elaborate escape from an Orange County jail on Friday are still in the region.

County sheriff's officials had a Vietnamese-speaking deputy appeal for public help during a press conference Monday.

Orange County has a large number of Vietnamese-Americans, and Lt. Dave Sawyer said officials believe 20-year-old Jonathan Tieu and 43-year-old Bac Duong may be "embedded" in the community.

The two men and 37-year-old Hossein Nayeri were awaiting trial for violent crimes when they vanished Friday.

The men somehow cut through metal, got into plumbing tunnels and rappelled from a roof using braided ropes made from linens.
