It’s a case that’s dragged on for 11 years.

"What we know, on July 8, 2006, early morning — roughly around four in the morning — Darren Greschuk and his wife were sleeping in the house,” Det. Staff Sgt. Vince Ashmeade says.

“They both woke up to an intruder in the house, and while trying to get the intruder outside the house, a struggle ensued between Darren and the intruder. And Darren was shot.”

The intruder fled. Greschuk, 31, died in hospital two weeks later.

No one has been charged, but the investigation is still active, Ashmeade says.

“Any tip that does come in on it, we are following up on it.”

Police always follow up on tips for homicide cases, even those cases several years old, according to Ashmeade. But what's different now is changes in the police service structure that allow a more targeted response to specific cases.

"In 2006, for this file, I believe there were two lead investigators who were called out,” Ashmeade says. “Compared to now, on a file that comes in, there would be at least four investigators plus a team of members who would come out to assist — 10 or more.”

He says police sometimes deliberately keep details out of the public eye to not compromise the investigation or to avoid numerous false leads.

The popularity of social media can help investigators find clues and ask for help. Sometimes, leads come from gossip on the streets.

In the Greschuk case, detectives believe more than one person was involved and say those connected to the case shared information with others.

That information could lead to an arrest, according to Ashmeade.

“The people involved had been speaking, and in certain circles that was being shared around. The truth is out there. It's just a matter of seeking and putting it together,” Ashmeade says. “The sooner we get that information that puts us over the top, it will benefit us toward closing that file.”

Nothing indicates the Greschuk murder was gang-related, Ashmeade says.

Investigators are hoping someone will come forward or leave a tip to bring closure and a killer to justice.
