A KIDNAPPED woman’s life-or-death plea to cops led to a heroic rescue — and the discovery of a serial killer!

And the psycho suspect’s own mother compares to savage murderers Ted Bundy, Jeffrey Dahmer — and even the Devil himself!

Ohio resident Shawn Grate was arrested Sept. 13 after the abducted victim secretly managed to get hold of his cell phone to dial for help, cops say.

“I’ve been abducted,” the desparate woman whispered, “Please hurry.”

Cops quickly rescued the woman, whose name has not been released, and — in the process — discovered two dead bodies!
