Let's not forget the evidence from Helene's diary, of a hateful man:
"A third entry read to the court - a year after Ms Dawson, 33, vanished from Sydney's northern beaches in January of 1982 - said Mr Dawson came to her house to drop off Lynette's belongings in 10 black garbage bags.
"The former Newtown Jets rugby league player and high school teacher was reportedly 'sick' of having the bags in his study and had packed items such as Ms Dawson's gardening gloves, nursing uniform and badge and a garter that she wore on their wedding day, the court heard that an entry read."
