Perth teen, 16, arrested for allegedly stabbing mother to death

A 16-year-old boy has been taken into custody after allegedly stabbing his mother to death and attacking his 12-year-old sister at their home in Bentley, a suburb in Perth's south-east. The incident occurred around 6:15am on Tuesday, prompting a swift response from police who arrived at the Mill Street residence to find the body of a 35-year-old woman.

The teenage suspect is accused of turning the knife on his younger sister, who managed to escape the house and run to a nearby highway to seek help. Officers located the mother deceased inside the home, while the girl was transported to hospital with stab wounds. Acting Insp. Jessica Securo confirmed to reporters that the girl is receiving treatment and is expected to survive.

Incident Details

Authorities say the attack took place early Tuesday morning, shocking what is typically a quiet residential area. Acting Insp. Securo stated that the female victim was found after police forced entry into the home. The 12-year-old girl's quick thinking in fleeing the scene and flagging down help likely prevented further tragedy.

Police have not disclosed the motive or the type of weapon used, but confirmed that a knife was involved. The 16-year-old boy is currently in police custody and is expected to face charges in relation to the incident. Investigators are piecing together the events leading up to the stabbing.

Victim and Response

The deceased mother has been identified as a 35-year-old resident of Bentley. Acting Insp. Securo expressed condolences on behalf of the force, saying, “Our thoughts are with them all, particularly the 12-year-old girl who remains in hospital receiving treatment. We ask that their privacy be respected during this investigation.”

The injured girl is described as being in a stable condition, and police are providing support to the family. The broader community has been rocked by the violence, with neighbors expressing shock at the early-morning incident.

Community Impact

Acting Insp. Securo emphasized that there is no ongoing risk to the wider community, stating, “I can confirm there is no ongoing risk to the wider community. This incident will have a significant impact on the family, friends and loved ones of all those involved as well as the broader community.”

Local residents have been left shaken, and police have increased patrols in the area as a precaution. The school community, if applicable, may also be affected given the ages of those involved.

Investigation and Next Steps

Detectives from the Major Crime Squad have taken over the investigation. The 16-year-old suspect remains in custody and will be processed through the justice system. Given his age, he will likely appear in a children's court, and the court may consider detention or bail conditions.

The incident adds to a series of violent family tragedies in Australia, prompting discussions about youth mental health and domestic violence prevention. Police will continue to investigate the circumstances, and further updates are expected as forensic evidence is analyzed.
