Wyoming authorities say they have rescued two young women being taken to California by human traffickers.

The Rawlins Times reports that Wyoming Highway Patrol Officers approached a car at a Shell station near Rawlins last week in response to a call about a disturbance.

A woman in the back seat mouthed the words "help me" to one officer.

Her plea led to the arrest of the 38-year-old male driver and a 27-year-old woman, both from California, on human trafficking charges.

Police say the woman who asked for help and another female passenger say they left Philadelphia with the couple because they promised them jobs and a new start in California. But the women say the couple became threatening and wouldn't let them leave once they got out of Pennsylvania.
