Residents of an Abbotsford home are wondering why their house was the target of a drive-by shooting on Saturday night.

Police were called to the 27600 block of Signal Court. A teenager was home with his grandfather when he heard loud bangs.

“I was scared. I thought they were aiming for someone,” the youth, whose name has been withheld for safety concerns, told CTV News. “I thought someone was throwing rocks at the windows or something.”

He said he made sure his grandfather was sitting away from the windows and took cover himself.

“I was rolled up into a ball next to the wall. It was just for safety,” he said.

One of the bullets went through the living room wall where the teenager's grandmother had slept the previous night.

“I was really emotional about that,” he said. “What if my grandma stayed one more night?”

Some neighbours who heard the gunfire thought the sounds were fireworks.

“Just heard a couple gunshots,” said Jordan Dunne. “I guess it was about six… then looked out the window and saw a van take off.”

Security video from Dunne’s home shows the van parked outside the targeted home before it drives off, running a stop sign as it leaves the area.

Dunne found shell casings outside when he went outside about ten minutes after the shooting. He has given his video footage to police.

“The residents in the house are cooperating,” said Abbotsford Police Sgt. Judy Bird. “At this time we are unsure what the motive was.”

Abbotsford police canvassed the neighborhood and searched the area for any people or vehicles that may have been involved. The people in the targeted home are not known to police.

Neighbour Rachpal Rangrhoo said the incident is particularly worrisome for families in the area.

“I was so scared. We have kids at home, little kids. They can fire at any house.”

The Abbotsford police forensic team is collecting evidence and the Major Crime Unit has taken over the investigation.

Anyone with information is asked to call the Abbotsford Police Department at 604-859-5225, text 222973 (abbypd), or call Crime Stoppers at 1-800-222-8477.
