Sharyn Allan lives directly accross the road from the property in which the fighting filtered out from, but says she barley heard the commotion from the back of her house.

"I woke up this morning and my house was covered in police tape and there was an ugly big pool of blood on my driveway," Allan said today.

"So I've been a bit upset all day, thinking I didn't get out of bed. Not that I could have done anything."
