Coolidge v. New Hampshire

While Edward Coolidge (defendant) was cooperating with a murder investigation, police obtained evidence from his wife and sought arrest and search warrants, including one for his Pontiac, from the state attorney general — the same official in charge of prosecuting Coolidge — acting as a justice of the peace; police then had the car towed and later found microscopic evidence used to convict Coolidge at trial over his suppression motions. The state supreme court affirmed his conviction, and he petitioned the U.S. Supreme Court.
