CAN YOU HELP SOLVE THESE MURDERS?

FORMER POLICEWOMAN DEBORAH WALLACE IS DETERMINED TO CRACK AUSTRALIA'S COLDEST CASES

- Megan Rowe

$3 MILLION REWARD!

Retired Detective Superintendent Deborah Wallace is making it her mission to finally give a grieving husband the truth about his wife's brutal murder.

This June marked 50 years since Sydneysider Paul White discovered his wife Lynette's bloodied body in their Coogee unit.

Lyn, 26, had been stabbed 11 times and her throat slit. The couple's 11-month-old son Shane lay in his bassinet, crying, just one metre away. He'd been there for hours as his mother lay dead on the floor.

Lyn's murder is still considered one of Sydney's most brutal crimes. Paul has never given up hope of finding his wife's killer, and is now hunting for answers alongside Deborah in the investigative TV series Million Dollar Murders.

The series cracks open three cold cases, including Lyn's. Deb tells New Idea she jumped at the chance to bring the unsolved homicides, all tied to a $1 million reward, back to life.

"It's the icing on the cake when this happens, because we know a whole hour will be dedicated to the stories of their loved ones with the hope of bringing justice for the terrible tragedy they've suffered," Deb explains.
