Days after her grandfather was gunned down outside his home, a B.C. woman and her family are asking the suspects to come forward to police.

Ping Shun Ao was standing in his yard in Abbotsford, B.C., on Wednesday when a spray of bullets -- originally aimed at his neighbour's home -- pierced the fence and killed him.

The 74-year-old lived next door to a home known to police, and investigators say Ao was likely caught in the crossfire of a gang-related shooting.

"This was essentially a neighbour standing by a fence at the time of the targeted shooting next door," Const. Ian MacDonald told CTV Vancouver.

The death has left Ao's family grief-stricken.

"We're all still in shock," his granddaughter told CTV Vancouver. "We would have never imagined it, him leaving us like that."

Ao's grandchildren described him as a loving family man who liked to spend time in his garden.

"He pretty much taught me everything I know today: Always be nice to others and they will do the same in return, always respect your elders, and have manners no matter where you are," his granddaughter said.

Now reeling from Ao's death, the family is worried gang activity in the area is putting their community at risk. Out of fear for her own safety, Ao's granddaughter asked the media not to identify her.

She said two other grandchildren who were in Ao's home at the time of the shooting are also scared of further violence.

"(The other grandchildren) heard the gunshots and when they called for Grandpa to see where he was, there was absolutely no response," Ao's granddaughter said. "They were terrified."

Police are now looking for a black SUV that was seen fleeing the area following the shooting. They're also asking the suspects and their families to come forward with information on the case.

"No more stonewalling, no more silence. This is where we do something about it," MacDonald said.

Ao's family is also appealing to the people behind the shooting, asking them to think about their neighbours' safety.

"I hope that they know that they're putting innocent people and young children in danger due to the activities they choose to be involved with," Ping's granddaughter said. "I hope they realize that changes need to be made."

Anyone with information on the case is asked to call the Integrated Homicide Investigation team tip line at 1-877-551-4448, or Crime Stoppers at 1-800-222-8477.
