By Australian Associated Press and Sally Lee The evening of 11-year-old Luke Batty's murder remains very clear in the memory of mother Rosie Batty. She recalled the moment her ex-partner Greg Anderson turned up with a 'big smile' at his son's cricket practice in Tyabb, south of Melbourne, on February 12 but soon after she heard a 'very disturbing sound'. 'I ran towards the sound because I didn't understand what it was and I could see Greg kneeling beside Luke and I thought, oh my God, he's done a fast bowl to his head and he's knocked him out and he's really hurt him,' she told the ABC program Four Corners.
