Three police investigations and two coronial inquests have failed to find out what happened to Leslie Ball, who vanished more than 30 years ago. Investigative reporters Jo Townsend and Callum Denness have spent two years trying to unravel what happened to the war veteran and grandfather as part of news.com.au's six-part true-crime podcast series Perfect Alibi. They’ve tracked down family members and former police investigators, uncovered evidence of fraud, and found links to the Melbourne underworld. They have also uncovered proof they say identifies who killed Mr Ball. 
The podcast launches on August 10, with new episodes dropping every Monday and Wednesday.
