'Hurry up and die, quickly': Son of serial killer Catherine Birnie says she should die in prison

One of Australia’s most evil serial killers is trying to recast herself as a reformed woman, but Catherine Birnie’s youngest son wishes she would “hurry up and die”.

It’s been nearly three decades since Birnie was jailed, after she and her husband were arrested for abducting and killing four women.

Their final victim Kate Moir managed to escape alive.

In her time behind bars Catherine Birnie has attempted to recast herself as a harmless prison librarian, who even starred in a prison production of the musical comedy, Nunsense.

While there are those who argue she’s served her time and should be released, her family strongly disagree, especially her youngest son Peter.

Kate Moir found an unlikely ally in Peter, in her fight to change Australia’s parole laws to stop killers like Birnie from ever being released.

Peter told Channel Seven's Murder Uncovered that he was “emotionally destroyed” knowing his mother was a serial killer.

Peter was only six when his mother abandoned her family to link up with David Birnie.

“I have been bashed over it. I’ve lost my teeth in my gob over it, I’ve been knocked out,” he said.

After she was caught Birnie wrote a chilling letter to her children.

“I never stopped loving any of you kids I am not proud of what has been said about me but I have to live that and the memories,” she wrote.

“Maybe you’ll write to me because I really like to hear from all of youse (sic). I love you kids.”

David Birnie was a father.

Peter said he was occasionally taken to visit Birnie in jail, but eventually it became too hard for him and he cut contact with his mother.

“She wants to see me, she wants to see the rest of the family,” he said.

He believes she is reaching out because she is eligible for parole.

“She wants to get close to one of us family members to say 'oh yeah they can take on the responsibility if you do get out'."

But Peter firmly maintains he does not want his mother to be released from prison and supported the death penalty for her.

David Birnie was a father.

“I reckon it is an eye for an eye, anyone who takes someone’s life should not be allowed to live themselves,” he said.

“I don’t have a mother mate,” he said when asked about whether his mother deserved to die for her crimes.

When asked if it would bother him if she was executed he said he “would party for a week.”

“It wouldn’t bother me. It would be 30 years of stress off my shoulders.”
