A third person has died as a result of a vehicle crashing into pedestrians at a National Day for Truth and Reconciliation event in Tsawwassen, B.C., according to local police. The Delta Police Department said in a statement Wednesday that 64-year-old Gwenyth Brigit Dwyn had died in hospital as a result of injuries she sustained in the Sept. 30 crash. Dwyn is the third person to die in the crash. Tsawwassen First Nation elders wilapiya—also known as Barb Joe—and Virginia Splockton died at the scene. A fourth individual has been released from hospital and is recovering at home, the DPD said. The tragic incident occurred as community members gathered ahead of the unveiling of four traditional carvings known as house posts outside Tsawwassen Mills mall. Police have previously said they suspect the driver of a pickup truck that slammed into the crowd was experiencing medical distress. In its update Wednesday, the DPD said its investigation is ongoing and “the possibility that the driver experienced a medical event prior to the collisions remains under investigation.” “Based on the evidence reviewed to date, investigators have not identified evidence indicating that the collision was targeted or ideologically motivated,” the statement reads. Police said their thoughts remain with the families and loved ones of the victims as they conduct “a thorough and methodical investigation.” Vehicle was involved in ‘earlier collision’ So far, the investigation has included reviews of “a substantial volume of evidence,” including interviews with “numerous witnesses” and multiple videos of the event. “Investigators have completed extensive scene and collision analysis and continue to examine all available evidence relevant to determining exactly what occurred,” the DPD said, in its statement. “This work includes examining the movements of the involved vehicle on the Tsawwassen Mills property before the pedestrians were struck, including an earlier collision. Investigators have not reached any final conclusions regarding the cause of the collisions.” Police did not elaborate on the location or circumstances of the earlier collision. Investigators are still working to determine what happened, police said, adding that any potential charges stemming from the incident will be forwarded to Crown prosecutors for assessment. “We understand that the community has questions and wants answers about what occurred,” said Staff Sgt. Mike Whiteley, in the statement. “Our responsibility is to ensure those answers are based on a complete and objective examination of the evidence. Investigators are working through a significant amount of information, and it is important that we not reach conclusions before that work is complete.” Police renewed their appeal for witnesses, asking anyone who has not already spoken to investigators to contact them at 604-946-4411 and reference file number 26-18401.
