A Queensland woman has admitted leaving her two young children in a parked car for nine hours leading to them suffering a death that "defies description".
Kerri-Ann Conley, 30, of Waterford West suburb in Logan, pleaded guilty in Brisbane Supreme Court on Tuesday to two counts of manslaughter.
Crown prosecutor Sarah Dennis said Conley had taken her daughters Darcey-Helen, aged two-and-a-half, and Chloe-Ann, aged 18 months, to her friend's place at 11.30pm on November 22, 2019 and returned home at about 4am the next day.
