When kidnapped become brainwashed

Kidnappers and their victims often develop complex relationships that seem unfathomable on the surface. Former LAPD psychologist Kris Mohandie calls a victim's attachment to a kidnapper primitive, and part of survival.

In some cases, Stockholm Syndrome is a factor in that bond. It can be the reason victims don't try to leave even when they have the opportunity to escape. Fear and a sense of having no power are also part of the emotional turmoil that can prevent someone in captivity from breaking free.

CNN's Randi Kaye reports on cases where the victims experienced brainwashing or psychological trauma.
