A neighbour told the ABC he heard screaming and a loud bang at the time.

This morning the victim’s daughter Jessica paid tribute to her father.

“The best way to describe him was as a kid at heart,” she said.

“He was a loving and caring person, I don’t think he deserved this.”

A 31-year-old woman was arrested at the scene and taken to Kogarah Police Station.

The ABC understands the woman was in a relationship with Mr Caetano.

Officers from St George Police Area Command and the State Crime Command’s Homicide Squad are investigating the circumstances surrounding the incident.

They were searching for finger prints and donned breathing apparatus at the house this morning.
