According to Gavin de Becker, knowing how one person fought off a specific abductor isn't much use if you are abducted yourself.
The reason is that perps vary. There are some that if you fight back, the perp will back off and may even run (Ingmar Guandique was apparently one of them; at least two women fought him off after he'd killed Chandra Levy). There are other perps that will intensify the sadism of their attack if the victim fights back.
Gavin de Becker's advice? Listen to the voice within and in an emergency, act on it without second guessing yourself.
There's a whole lot more good information and advice in his book The Gift of Fear.
