It is now ten years since outspoken Indo-Canadian newspaper publisher Tara Singh Hayer was murdered, and still his family continues the search for justice.

The passage of time hasn't dulled the pain for the late publisher's son Dave Hayer and his family.

That's not just because their father was murdered. It's also because after 10-years, his killers are still eluding justice.

Tara Singh Hayer was gunned down in November 1998. He was putting the final touches on the latest edition of his Indo-Canadian newspaper, a publication that didn't waiver in its criticism of extremists trying to import terror to Canada.

"Once he made up his mind he wanted to stand up for something, he did and you couldn't change his mind and that shows you even the bombing attempt at his office in 1986, the shooting in 1988 and he still held the same view, you can't bring terrorism here," said Dave Hayer.

While that dedication to principle ended up killing Hayer, his family says it would be easier to move on if those responsible had been punished.

The RCMP have an ongoing investigation. But so far, it hasn't yielded results.

"One of the factors that is proving difficult is there were multiple plots to kill Mr. Hayer over an extended period of time and now with the passage of time, the fact it's been ten years, it makes it even more difficult," said RCMP Sgt. Tim Shields.

Perhaps nowhere did Tara Singh Hayer's murder have more of an impact than at B.C. Supreme Court where it may have played a crucial role in the lack of justice for one of our country's most horrible crimes.

That crime was the Air India bombing. Hayer was set to be a witness in the trial, testifying against Ajab Singh Bagri, one of the men acquitted in the case.

"It could have been very, very compelling evidence. Of course it was lost His statements were not allowed to be entered as exhibits in that case and we'll never know what could have happened if he had been alive to testify," said Kim Bolan, a Vancouver Sun reporter, who has written extensively about Air India.

But Dave Hayer has tried to move beyond that. He's now focused on two things -- the need for justice - and the need for the public to not forget what his father died for.

"We have to make sure that our future generations also realize that we can't allow this to repeat, We can also make sure that we don't allow people to allow terrorism to come here," he said.
