Police taps on Chris Dawson’s phone in 2018 as episodes of The Teacher’s Pet were unfolding reveal him and his twin brother Paul raging over the former babysitter-cum-wife JC, as well as journalists, TV crews and homicide cop Damian Loone. In one intercept Chris discloses he was still hearing from Lyn some ‘six or eight weeks’ after she disappeared - although in 1982 he told police his contact with Lyn ceased after a week. He says of Lyn: 'she took off'. The evidentiary value of bruises described by witnesses on Lyn’s arms, neck and leg is weighed by the judge as the trial reaches its pointy end.
