A TEENAGER has been arrested after he allegedly fatally stabbed his father and critically injured his mother this morning.
Police were called to the family home in Baulkham Hills, Sydney, about 7.15am after reports a couple had allegedly been attacked with a knife by the youth.
A middle-aged man died at the scene in Bernadette Place, shortly after paramedics arrived.
A woman, 40, was treated at the scene for multiple stab wounds and was taken to Westmead hospital, an ambulance spokeswoman said. Her condition is said to be critical.
Police arrested a 16-year-old boy at the house and he is assisting officers with their inquiries.
I've just heard that his mother has died from her wounds after being rushed to hospital. I can't even begin to fathom what drives people to do something like this. I went through some teen angst as most people do, I certainly argued with my parents and I even played violent video games if we're going to throw that theory out there but I could not imagine being motivated and willing to take someone's life, especially my parents'.
UPDATE: Apparently the report that the mother had also died is false, though she remains in a critical condition.
, i just said that because that's my theory of want happen.
