Karla Homolka's ex-lover Lynda Veronneau warns that Homolka is a master manipulator, in an exclusive interview with CTV's Jennifer Tryon.

"I want to show the people who she is, that woman," she says in broken English. "… and I think I am the only person to know how she is."

Veronneau and Homolka were involved in a relationship for almost four years. It began in 1998 while both were incarcerated in Joliette Institution in Quebec. Homolka ended the affair in 2001 after Veronneau had been released.

They first met in the cafeteria, then later shared a prison condo. When Veronneau found out about Homolka's past with Paul Bernardo, she says was already in love.

Homolka told Veronneau she was a victim in the brutal murders of Kristen French and Leslie Mahaffy.

"I always felt she was the victim in this because she's very good at saying she's the victim," she says in French.

But Veronneau says she no longer believes Homolka's claim. Veronneau says that Homolka received a plea bargain, resulting in a 12-year sentence, by "saying she's the victim."

She also says the public is right in its anger at the so-called "deal with the devil," which enabled Homolka to avoid the same life-sentence as her husband.

"They're right," Veronneau says. "And she knows. She knows that the public hates her because of that. Because she got 12 years for what she did, and they're right."

Asked if Homolka cares about the public's opinion, Veronneau responds: "She's scared."

After Veronneau was released from prison, Homolka fell in love with another inmate -- the convicted killer and French national Jean-Paul Gerbet.

"She could have been with a plumber, with a taxi driver," Veronneau says in French. "Anything, but not another killer."

Veronneau is unsure if Homolka will be a danger to society when she is released, but believes if she does commit a crime it will be through manipulation.

Pat Brown, an investigative criminal profiler, told CTV's Mike Duffy she has no doubt Homolka will re-offend when she is released.

"I hope we just keep a real watchful eye on her, because she will re-offend if she can," she said Thursday during CTV Newsnet's Countdown: with Mike Duffy. "She's a psychopathic, pathological liar, and she's a serial killer and will be until the day she dies."

Stephen Williams, author of Karla: A Pact with the Devil, disagrees. As one of the few journalists who has been in contact with Homolka, he believes she is not a serial killer.

"The psychiatrists have, over the years, evaluated Karla and come to certain conclusions, most of which don't agree with Ms. Brown's opinions," he said.

Both Brown and Williams find it difficult to believe what Veronneau says about Homolka.

"Frankly, Lynda Veronneau is a career criminal with a record longer than her entwined arms and legs," Williams told Duffy. "To be perfectly blunt, I'd believe what Karla said before I'd believe what Lynda Veronneau said."

Veronneau says she has much more to tell the public about Homolka, and is currently writing a book about her ex-girlfriend.
