VANCOUVER -- It’s been three agonizing weeks since Bernard Grempel’s family has heard from him. “This is so uncharacteristic. We're worried that he's hurt or he's scared or he's in danger somewhere,” said Ettie Shurack, Grempel’s sister. Grempel, 28, was last heard from on May 14. According to his bank card and transit pass activities, he went to a 7-Eleven at at 152 Street and 100 Avenue at 8:44 p.m. before boarding the SkyTrain at Surrey Central Station at 10:30 p.m. He arrived at 22nd Street Station in New Westminster and boarded the 340 bus. Shurack said that is typically the route he would take to visit their parents, and finding out where he got off transit should have been much easier.
