An "agitated" Paul Bernardo insisted Tuesday that his ex-wife, Karla Homolka, attempted to murder Ontario schoolgirl Leslie Mahaffy on her own.

Speaking through his lawyer, Bernardo said on Tuesday that he has been thinking about the release of Homolka, his co-rapist and co-killer, who was set free on Monday after serving 12 years for her part in the killings of Mahaffy and Kristen French.

Bernardo was convicted of two counts of first-degree murder and sentenced to life. He was later declared a dangerous offender, which will keep him in prison indefinitely.

But with media attention focused on his ex-wife, Bernardo couldn't resist speaking out on Homolka, talking first with Ontario police on Friday, then with his lawyer Tony Bryant.

"He became agitated maybe as a result of seeing all the media attention over the last several months," said Bryant.

"There's a couple of things that he wanted to say that he thought were particularly troublesome."

Bernardo is not allowed to speak publicly.

Bryant said his client wants people to know that after the kidnapping of Mahaffy, during the rapes, Bernardo was still planning to set the teen free. But Homolka panicked and attempted to murder Mahaffy.

"He wanted to get the message across that she actually tried to kill Leslie Mahaffy by means of an embolism. By means of injecting an air bubble into her bloodstream. Because she was afraid that because the blindfold had fallen off, that she [Mahaffy] would be able to recognize Paul [Bernardo] and presumably herself," said Bryant.

Those specifics make for a story Bernardo's never before told.

But they differ little from his insistence during his trial that it was Homolka who strangled Mahaffy and later French.

"He's saying 'Look, I told you once and it didn't sort of have much of an impact. I don't want anyone to ever say 'Well why didn't you ever speak to the only person who really knew her while these events were going on?'' He would be the one to be able to tell you what she was really like, and so now he's doing it."

Bernardo also reminded Bryant that Homolka helped out on a less reported kidnap and rape before Mahaffy.

But even if the new specific allegations are proven, Bryant says they'd change nothing for Bernardo's sentence, nor would they have any effect on Homolka's freedom.

Neither the police nor Ontario's Crown Attorney's office would comment on the allegations.

It's Bernardo's understanding that he may get the chance to speak publicly when the fuss over Homolka's release dies down.
