A de facto carer who instructed two intellectually disabled people to participate in sex acts while he filmed them has been jailed for at least two-and-a-half years. The 55-year-old-man, who cannot be identified for legal reasons, was found guilty of two counts of rape and two counts of indecent filming, and pleaded guilty to threatening another carer who found out about the abuse. South Australia’s District Court heard the man had been a de facto carer to a young intellectually disabled woman.
