A 16-year-old boy is charged with murder and attempting to kill after his mother dies from stab wounds and his 12-year-old sister is seriously injured, police allege. Multiple reports say the incident occurs in Perth’s south-east. The woman is fatally injured, while the younger sister is found seriously hurt. One account says the sister manages to flee to get help after the attack. Authorities charge the teenager following the alleged stabbing of his mother and the separate stabbing of his sister. The reports consistently describe the charges as murder and an attempt to kill related to the injuries suffered by the 12-year-old. Details about a motive, the exact circumstances leading up to the stabbing, and the teenager’s alleged actions beyond the alleged stabbing are not provided in the excerpts. The matter is before the courts, and the accused is presumed innocent unless proven otherwise.
