Rose Elvira Montoya de Hernandez entered the United States at
Los Angeles International Airport from
Bogotá,
Colombia. Customs inspectors detained Montoya de Hernandez upon her arrival based upon a suspicion that she was smuggling drugs. After 16 hours and a rectal examination by a physician that produced a balloon containing a foreign substance, she passed balloons filled with
cocaine from her
alimentary canal. The defendant had claimed that she was pregnant, and she was given the opportunity to undergo an
X-ray, but she refused after being informed that she would have to be handcuffed en route to the hospital. Over the next three days, the defendant passed 88 balloons filled with over of cocaine. At trial, Montoya de Hernandez alleged that her
Fourth Amendment rights were violated by an unreasonable detention. The U.S. government contended that the inspectors had
reasonable suspicion that the defendant-respondent was a drug smuggler. She had a noticeable bulge in her
abdomen when she was detained, and a female inspector searched her revealing that Montoya de Hernandez was wearing two sets of elastic underpants and had paper towels lining her crotch area (as balloon swallowing makes
bowel movements hard to control). A federal district court disagreed with Montoya de Hernandez's Fourth Amendment claim, and she was subsequently convicted for federal
narcotics offenses. The
United States Court of Appeals for the Ninth Circuit reversed the district court's conviction, on the grounds that the district court had incorrectly refused to suppress evidence used against the defendant. The federal government appealed to the U.S. Supreme Court, which granted
certiorari. ==Decision==
