She folded the clothes Jye had been gifted on Christmas Day, but hadnt lived long enough to wear. She paused over one of his socks, found abandoned in his bed sheets.

I was putting his things away and behind the drawer there was a little box, Scottish-born Kathy McWatters told the Mercury.

And he had $7.20 in it. I thought, poor little bugger. He must have been [saving up] his 20 cents.

Mrs McWatters cannot believe that Jye, 19, had any secrets bigger than his money box. He told everything to the grandmother who reared him, she says.

She knew he smoked pot. He would tell her when he was going out to try to get onto a girl and when he succeeded. If he were involved in something sinister, she feels like she would have known about it.

And yet someone disliked Jye enough to shoot him in the back of the head.

There are whispers about Jyes final moments that disturb his family. And threats real or imagined make them worry for their safety.

Passers-by are always pointing at the house. Members of the family hid from a stranger who knocked on their door recently and Mrs McWatters wonders at the motive of the person who slashed the tyres of her car, parked in the homes driveway.

Fifteen months on, with Jyes killer still not caught, the family lives in fear.

You think, they got Jye for as far as we know - no reason. So are they coming back to get us? Mrs McWatters said.

Jyes body was found in the front yard of Mrs McWatters Kippax Street home on Boxing Day 2015. He wore only boxer shorts. He lay partly beneath a trailer, with two garbage bins pushed in front of him.

He had asked his grandmother if he could go out the night before only down the street but Mrs McWatters had talked to him when he came home soon afterwards, returning the sentiment when he told her, love you Nan, before both went to bed.

Jye's brother Jaydan rose early the next morning, wanting to go skateboarding, but his grandmother made him wait. It was Jaydan who discovered Jyes body about 10.30am, when he at last went outside.

He yells, Nan, Nan, Jyes dead, Jyes dead! Mrs McWatters said.

I said, Jye isnt dead. Hes in bed.

I couldnt go out. I went to the front door; I couldnt look at him.

Mrs McWatters initially believed Jye had fallen and accidentally hit his head. She became fixated on her grandsons final moments when detectives told her the truth of how he had died.

I said, did he suffer? Because I was hearing all this stuff. I was hearing that Jye was taken away. That they tortured him. That theyd done all this it was driving me crazy, she said.

I said to the head detective, just tell me one thing: did Jye suffer?

He said no, it would have been just like lights out. The bullet would have hit the back of his head.

It is getting harder as time goes on to be without Jye, Mrs McWatters said. She often wonders what could have compelled him to get up and leave the house after he went to bed Christmas night.

She keeps coming back to the theory that a girl might have called him out, because he had followed a female voice to the door at least once before.

They played music fit for a gangster at his funeral, but his grandmother will remember him dancing to Cat Stephens Im Being Followed by a Moonshadow.

He was a clown in a crowd, she said. Dont get me wrong. He was a typical 19-year-old boy. If he didnt get what he wanted, hed put on a tantrum. But I would have that tantrum back in a heartbeat. He could smash my whole house up, but Id still have him back.

There must have been a reason he was [murdered], but he wasnt a bad boy.
