West Vancouver police have ramped up their investigation into a shooting Saturday night that injured three people on the Squamish Nation's Capilano Reserve.

The shooting took place shortly after the annual Squamish Nation Powwow ended for the night, sending two men and a woman to hospital.

"We're making headway in the investigation," said WVPD spokesperson Cpl. Fred Harding. "Significant resources have been attached to this file which means we have a full investigating team. We have officers called in on call out, we have officers reassigned from their current duties to this investigation, we have forensic intelligence officers, we have inter-agency assistance, we have a crime analyst and we have access to other Lower Mainland resources as of when we need them."

Harding added police are searching for a male suspect.

Police believe the two male victims were targeted in the attack while the woman was an innocent bystander. At least four shots were fired outside of the powwow grounds at Xwemelch'stn shortly after 11 p.m. on Saturday.

Harding said the Integrated Gang Taskforce has been "consulted," but are not currently involved in the investigation.

The woman has since been released from hospital, while the two men remain in care. Their condition is not known.

Harding said the two men were asked to leave the powwow grounds just before the shooting. He added he did not know if the shooting and their expulsion were connected.

"That place is sacred ground (at the time of the powwow)," Harding explained. "I know they were asked to leave... I believe it was related to alcohol consumption."

Deborah Baker, who helped organize the Squamish Nation Powwow, said the shooting has shocked the nation and participants.

In its 22 years, Baker said this was the first incident of violence to her knowledge.

"That's why it has been so dramatic... we do not tolerate violence in our community," Baker said.

Baker added that despite the powwow ending for the night, many stayed behind to participate in healing songs for the victims and shooter.

"It is in the opinions of the organizers that the suspect probably needs serious help and hopefully he will get proper guidance...." Baker said.

While police have ramped up their resources to track the shooter down, Harding added they are looking to the public for help.

"We're making an appeal for anyone who may have taken video or taken photographs that night in particular in and around the entrance to the powwow grounds around the time the incident took place," Harding said.

People who may know the shooter were also asked to come forward.

"Somebody somewhere knows who the shooter is ... and where they are and we would ask them to find it in themselves to come forward and let the police know that information."

A special hotline has been established to handle calls for the investigation. It is 604-922-3888. Crimestoppers can also be contacted at 1-800-222-TIPS.

The shooting occurred on the eve of the 5th annual sex abuse rally that begins at St. Paul's Church and marches to the powwow grounds.

Harding said about 60 people began the march, which grew to 150 at the end.

"Certainly there was a lot of emotion at the beginning of the rally and at the conclusion," Harding said. "That powwow has been such a particularly peaceful and spiritual event for twenty-something years it was such an indignity to the people there... a lot of people are finding it hard to process what actually happened there."
