A father and son are expected to face federal kidnapping charges after they zip-tied two U.S. Forest Service employees and held them at gunpoint inside a trailer in Northern California near Mt.

Two U.S. Forest Service workers were held hostage for hours by a man with a gun in a California forest before they were freed, authorities said.

The employees were taken hostage by two armed individuals on Thursday while conducting fieldwork in Shasta-Trinity National Forest.
