I'm not scared, says girl after family murdered

SYDNEY - Orphaned Australian teenager Brenda Lin believes those responsible for the murder of her family were targeting her parents but she has no idea why.

The Cheltenham Girls High student was on an excursion to New Caledonia when her parents Min "Norman" and Yun Li "Lily" Lin, brothers Han "Henry", 12, and Tian "Terry", 9, and aunt Yun Bin "Irene" Yin, 39, were bludgeoned to death in their beds.

Police are yet to make an arrest or reveal a motive for the murders last month in the leafy, middle-class Sydney suburb of Epping where her family ran a nearby newsagent.

Brenda, 15, told 60 Minutes that she had no clues about the motive for the killings.

"I've got no idea because my parents were always really nice to all the customers and we never got threatening phone calls or anything so I have no idea why or who could do this," she said.

In spite of the horrific killings, she says she is not frightened.

"For my safety, not really because it seems to be personally aimed at my parents and my theory is that if they were after like the whole family, they would have waited until I came back from New Caledonia.

"I think I'm not really frightened."

Even after attending the funeral service for her family, the reality of the shocking murders is yet to sink in.

"I just couldn't believe they were in there [caskets]," she said.

"I still think they are alive and I just couldn't believe they were there."

Brenda delivered a taped eulogy before saying goodbye last week.

"I had to actually write the speech out beforehand.

"It took me quite a while to write because I wasn't sure what I should say. I haven't been to a funeral before."

Her aunt Cathy, who found the bodies, has promised to look after Brenda.

She said nothing was out of place and everything looked "normal" when she entered the family home and discovered the murder scene.

Brenda has since walked through the home and described it as "like an abandoned house".

"It seems so empty and like all the windows are covered with cardboard and stuff and you can't see inside," she said.

"I still think that I'm going to go back there and live, but I don't think so.

"I still expect my parents to be there."

The teenager revealed she and her late younger brother Henry had been "really close".

"It doesn't seem fair," she said.

Her mother was eager for her to study medicine or law while her father, a qualified engineer in China, wanted her to study engineering.

Brenda said her family, originally from China, loved living in Australia and she would move on with her life in Sydney.

"I really like it here in Australia and because this incident has happened it shows that so many people all around Australia are supporting me and I'm really glad that I live here and this is my home."
