Story summary

Five gun control advocacy groups have called for RCMP to release detailed information about the firearms used in the February 10 mass shooting at Tumbler Ridge Secondary School in British Columbia, which left nine people dead. The groups argue that transparency is crucial for preventing future tragedies and fostering informed debates on policy changes aimed at enhancing public safety from gun violence. However, the RCMP maintains that specific details cannot be disclosed as the investigation remains ongoing. At the time of the shooting, RCMP reported recovering two firearms: a long gun and a modified handgun. The advocacy groups have expressed their intention to continue pressing for information if it is not forthcoming soon, emphasizing the need for clarity on any withheld data and an estimated timeline for updates from the RCMP.
