A man stabbed outside a Vancouver Starbucks on Sunday evening has died, and his alleged assailant has been charged with murder, Vancouver police say. Paul Stanley Schmidt, 37, was stabbed outside the café at the corner of Granville and West Pender streets around 5:40 p.m. following a “brief altercation,” according to police. Schmidt was rushed to hospital, where he later died. The suspect, 32-year-old Inderdeep Singh Gosal, was arrested at the scene, and has since been charged with second-degree murder. Schmidt’s mother, Kathy, told Global News he was at Starbucks with his wife and his young daughter. “Paul lived for his wife and his daughter… that was his whole life,” Kathy told Global News over the phone. “This man has ruined so many lives” Vancouver police spokesperson Sgt. Steve Addison said police are appealing for more witnesses and video to help them determine a motive in the killing. “There’s a significant amount of evidence to tell us what happened. What we are focusing on now is why did this happen. What are the events that transpired in the moments leading up to this very serious crime … and that’s something that may take some time for us to fully understand,” he said. “We believe there are people likely nearby, people who witnessed it, people who were in the area who can help us to understand those questions.”
