Ziang Sung Wan v. United States, 266 U.S. 1 (1924), was a United States Supreme Court case concerning the admissibility of a confession in a 1919 triple homicide case. Scott Seligman, writing for the Smithsonian, referred to the case as having "laid the groundwork for Americans' right to remain silent".[1]
One of the victims of the triple murder was translator Theodore Wong.[2]
