A still-grieving mother remembered her murdered son Sunday, one year after the young man was an innocent victim in a brutal gangland slaying.

Eileen Mohan says it seems like yesterday she got the news no mother should ever hear -- that Chris Mohan was dead, killed in a Surrey apartment building along with four others and another innocent man, Ed Schellenberg.

"I know he's our angel in heaven, and I'm just praying to ask God to give me courage to live every day with strength," said Mohan.

The Lower Mainland's Integrated Homicide Investigation Team claims it has suspects in the killing of six men in the 15th floor of the Balmoral Tower in Whalley on October 19, 2007.

But with no arrests, it's unclear if or when anyone will be charged.

In the year that has passed since the murders, important clues haven't been passed on to the police, Mohan said.

"There is someone out there, family associates who know who did this to Chris and they should come out and talk about it," she said.

Since IHIT was formed five years ago, only 30 per cent of the drug or gang related murders have been solved.

One reason solving crimes like this is difficult is because people are reluctant to come forward for fear or reprisals.

And another reason is because dead gangsters don't talk, said B.C.'s Attorney-General, Wally Oppal.

"In cases like this, the police have told us, the people who committed these crimes may not be with us any more because they themselves get killed," said Oppal.

Until there is a conviction, Mohan keeps bringing flowers to her son's grave, keeping a flame lit, and praying for justice.
