I discussed the inevitable discovery exception in my last post. This post will discuss the independent source exception, particularly the United States Supreme Court cases of Segura v. United States, 468 U.S. 796 (1984), and Murray v. United States, 487 U.S. 533 (1988), and related North Carolina cases. It should be noted that the independent source exception was initially adopted in Silverthorne Lumber Co. v. United States, 251 U.S. 385 (1920), and can apply to investigations involving Fourth, Fifth, or Sixth Amendment violations.
