Airdate: Seven News investigates: The Devil You Know

On Monday Seven will screen a news special Seven News investigates: The Devil You Know.

Robert Ovadia looks closer at the murder of Jamie Gao, at the hands of former NSW detectives Roger Rogerson and Glen McNamara.

Criminal Minds: Beyond Borders is now expected to air as a single episode at 9:45pm.

On May 20, 2014, 20-year-old university student Jamie Gao was shot dead inside a Padstow storage shed in Sydney’s south west. Six days later his body would be found by fishermen, stuffed inside a surfboard bag floating off the Cronulla coastline.

Damning security footage put two men inside that shed with Gao – former NSW detectives Roger Rogerson and Glen McNamara.

Both pleaded not guilty to the shooting murder and a separate charge of taking part in the supply of 2.7kg of ice.

During the four-month trial Rogerson and McNamara pointed the finger at each other for the murder. Today, a jury found both men guilty on all charges.

Now, in a powerful one-hour special investigation, Seven News will examine in forensic detail the full, extraordinary facts surrounding the case.

Featuring incredible CCTV vision of the 48 hours before, during and after the murder, senior reporter and Walkley Award-winning journalist Robert Ovadia pieces together the events that led to Gao’s death and key evidence in the investigation.

We look back at the life and crimes of Rogerson, one of Australia’s most infamous detectives, and hear from the insiders who know him and McNamara best. And the shocking revelation from one of the most respected policemen in NSW history.

Monday 20 June at 8.45pm on Seven.
