A group went searching for Christmas trees in a California forest — and found a partially naked kidnapping victim instead, authorities said.

The seasonal search party on Monday stumbled across the 25-year-old woman suffering from exposure and wearing only shorts in a rural woodsy area of Redding, where she’d spent the night drinking from mud puddles and huddled in a burned out tree to survive the rain and snow.

The victim, who wasn’t identified, told officers she’d been taken Sunday afternoon by two people she knew, because they thought she’d snatched their drugs, police said.

She claimed Johanna Knighten, 33, and Fred Sanderson, 44, then physically assaulted her and forced her to strip to her shorts before leaving her in the forest six miles from the nearest highway Sunday.

Not knowing where she was and without any means of communication, she spent the night trying to seek shelter from the 30-degree cold.

On Tuesday, cops arrested Knighten after spotting her driving a white van the victim had described, officials said.

She was charged with kidnapping, attempted murder and conspiracy and is being held in Shasta County Jail.

The other alleged kidnapper is still at large, police said.
