Sydney grandfather Paul Streeter was murdered, family say

Police are still investigating the circumstances around the death of Paul Streeter, 54, who was found by his wife Kathleen in a pool of blood out the back of his Miranda home at 7pm on Monday.

Mr Streeter had suffered extensive injuries to his upper body and detectives at this stage are treating it as suspicious.

His daughter, Brooke Streeter, told reporters outside her parent's Burrinjuck Place home that her father had met with foul play.

"My dad was murdered, we don't know why," she said late on Tuesday.

Ms Streeter said her father had recently come to visit her and her children, and that his behaviour was out of character.

"He said to me that he'd come to check on me ... and that he loved me," she said. 

"My dad doesn't really tell me that he loves me so it was like he knew something was going to happen to him.

"For him to come and check up on me ... he doesn't do that. He comes to have a coffee and to spend time with me and my girls but not to check up on me," she said.

Neighbours said Mr Streeter had three daughters and four grandchildren.

Resident Gabrielle Murray said she'd never seen any trouble on the quiet street.

"I have never had any trouble in this street, there is never any noise there are just kids playing and riding their bikes," she said.

Another neighbour, who didn't want to be named, expressed the sense of loss on the cul-de-sac.

"I gave [his wife] Kathy a hug and she started crying," she said. "She told me she touched the body and it was cold."

William Ryan, a long-term resident of Burrinjuck Place, said he had been a neighbour to the couple for about 20 years.

"It was quite a shock," he said. "A very sad affair, that's for sure."

He had last seen Mr Streeter as recently as the weekend. 

"He was a quiet guy, a nice guy. [There were] never any dramas."

Mr Ryan said he had been home from 4pm on Monday, observing the quiet street as he mowed his front lawn until dusk. 

It was a small cul-de-sac of just eight homes and anything out of the ordinary wouldn't go unnoticed, he said.

"It's one of those sort of streets that if another car comes out, you'd remember it," he said. He said the street had been especially still on Monday afternoon, with barely a flicker of activity.  

It wasn't until later that night, when police knocked on his door, that he learned of the tragedy that had occurred. Several hours later, Mr Ryan woke to the sound of a tow-truck removing a car, which he thought belonged to the couple, from the street.

In the two decades he has lived on Burrinjuck Place, Mr Ryan said he had never been burgled. 

"I'd be very surprised if it was a robbery. I've never had anything happen that would make me be more conscious of security," he said.
