Answers as to why a gunman decided to enter a Banyo house and take a mother and daughter hostage on Boxing Day may have to wait until a coronial investigation.

Police locked down a Banyo neighbourhood at 11.45am on Thursday following reports of gunfire from a house on Earnshaw Road. 

The woman and her teenage daughter were found shackled and bound inside the house by Special Emergency Response Team officers, who entered the home through an upstairs bathroom window, at 4.15pm.

The women were found to be “emotionally traumatised” but not physically injured.

But the siege continued until 7.25pm when police, using a robot and drone, found the gunman’s body in an upstairs room.

No one else was injured during the siege, although an empty marked police car that had been parked outside the home had been shot at.

Given the man died during a police operation, an ethical standards investigation has been launched.

But any other answers may have to wait until a coronial inquest is held, as police consider their part in the matter to be finished.
