The 74yo former schoolteacher convicted last year of the murder of his wife Lynette was found guilty yesterday of having a sexual relationship with an underage student. The girl – who was known in court only as ‘AB’ – described being “groomed” to engage in regular sexual activity with Dawson from the age of 16yo. After Lynette disappeared, Dawson and AB married and had a child – she gave evidence against him in this trial. Throughout the trial, Dawson denied being intimate with the teenager until she was 17yo (aka the age of consent) and pleaded not guilty. Dawson, who’s currently serving a 24-year sentence over his wife’s murder, will be sentenced over his latest conviction in September.
