A 16-year-old boy in Perth, Australia, has been charged with murder and attempted unlawful killing after allegedly stabbing his mother to death and wounding his 12-year-old sister at their home in Bentley, a suburb in Perth's south-east. Police found the 35-year-old mother dead when they arrived on Tuesday morning; the younger girl managed to escape the house and reach a nearby highway, where bystanders administered life-saving first aid before she was taken to Perth Children's Hospital in a critical but stable condition. The teenager appeared before the Perth Children's Court on Wednesday, and police described the attack as a deeply shocking incident with a significant impact on everyone connected to the family.
