Chinese-American officers made the long trek from California, Illinois, Canada and elsewhere to the funeral of New York police Detective Wenjian Liu not only because they lost a fellow cop, but because the story of the fallen officer was also their own. "When we saw the spelling of his name, we knew he was from mainland China, and we knew we had to go," said Toronto police Constable Qian L. Yang, an immigrant from China. "We have the same background, the same culture. We wanted to show our respect." Yang was one of thousands of mourners from many backgrounds and places who attended Sunday's funeral. Liu was shot to death along with his partner, Officer Rafael Ramos, as they sat in their squad car Dec. 20 in Brooklyn. Ramos was buried on Dec. 27.
