The mother of Sally Anne Bowman, the 18-year-old raped and murdered by Mark Dixie in 2005, has said her daughter would still be alive if Australian police had “done their job properly”. The comments come amid calls for a fresh investigation to be launched into the serial sexual offender’s time in Western Australia in the 1990s, when he was arrested three times but only charged for a more minor offence and never added to any kind of register. Dixie, now 50, was sentenced to life in prison in 2009 for brutally attacking and killing Bowman, an aspiring model, in Croydon, south London.
