‘Someone’s been hurt’

Ron Wenban lives two doors down from the property and had friends over when he heard a gunshot.

“It’s rare to hear one shot here,” he said.

“We were outside and I said to my partner, ‘was that a shot?’, and she said ‘yeah’.”

Mr Wenban said he didn’t know his neighbours well but that they lived in Sydney and had bought the property about five years ago to use as a weekend holiday home.

Shortly after the gunshot, Mr Wenban said he heard sirens and, about an hour later, an emergency helicopter flew overhead.

“Once the chopper came over, I said to my partner ‘someone’s been hurt’,” he said.

“To have a gunshot like that happen, that was a concern, neither of us wanted to go over there.”

A report will be prepared for the coroner.
