More CCTV has been released which capture Ivan Esack's movements in the hours before he killed his wife. He's first spotted in a supermarket, buying a kitchen knife.
He's then caught on camera parking his car - and then walking towards his wife Natalie's hair salon, where he stabbed her to death.
In this special report, by our Correspondent Derek Johnson, we also hear Esack's police confessions as he says "I snapped. I just snapped. I lost it."
