Dr. Kathleen Heide has interviewed some of the most violent criminals, and learned what made them tick.
She calls Ariel Castro calculated and brazen.
From her experience, Heide, who is a professor at USF, believes Castro's violent behavior did not start with the kidnapping of Michelle Knight.
Dr. Heide believes he may have had issues growing up. But it's even more likely his violent behavior started as fantasy where he would rehearse in his mind how to find and approach a girl, and then how to eventually grab a child.
After he was able to take Michelle Knight and not get caught, he likely got braver.
"There's this ‘success' and success reinforces more attempts. And more ‘success,' leads one to think you can continue to get away with it," Dr Heide explained.
And Ariel Castro did get away with it for at least 10 years. Dr. Heide says keeping the victims alive was done because he found they were useful to him.
"An individual like this, his sexual high may come from having the women in captivity, having them basically as sex slaves," Heide said.
And to add to the disturbing information that has come out, we learned from the women's family and friends that Ariel Castro attended a vigil for one of his victims, Gina DeJesus.
The family says Castro helped in the search for Gina, and even hugged Gina's mom during a search gathering.
Dr. Heidi says Castro may have wanted to see what family or investigators knew.
"It shows a lot of things -- [he] could be very cunning to see what's known and to avoid suspicion. So there could be a very calculated aspect. It's also indicative of someone with a total lack of feeling," she said.
Dr. Heidi says it likely gave Castro an addition feeling of power.
"It's sort of holding that card, that sense of power and control. But it's also indicative of someone who has what appears to be psychopathic traits. No conscience, no feeling, no empathy, no connection with a mother's grieving or a father's terror."
Dr. Heidi believes as the years went on, Ariel Castro's sense of power was reinforced.
"It'd be hard to think he didn't enjoy that sense of control or that sense of power. Or if he didn't, he would have released these women."
