Former rugby league star, Chris Dawson, has been handed over to the police in Sydney where he will be charged for the murder of his wife Lyn Dawson in 1982.

Mr Dawson was in a relationship with one of his students Joanne Curtis, 16, at the time when Lyn, then aged 33, disappeared. Ms Curtis moved into the family home two days after Lyn went missing.

All eyes are on the 70-year-old former Newtown Jets star and high school teacher as he is expected to be charged with the murder of his wife.
