Ignacio Flores-Figueroa, an illegal alien from Mexico, used a counterfeit Social Security card bearing his real name and a false Social Security number to obtain employment at a steel plant in East Moline, Illinois. Though he did not know it, the number belonged to a real person, a minor. The question in the case was whether workers who use false Social Security and alien registration numbers must know that they belong to a real person to be subject to a two-year sentence extension for "aggravated identity theft."

Specifically, the case hinged on whether the adverb "knowingly" applies only to the verb or also to the object in 18 U.S.C. § 1028A(a)(1) (which defines aggravated identity theft): "Whoever [...] knowingly transfers, possesses, or uses, without lawful authority, a means of identification of another person [...]".^[2][3]

In a unanimous decision delivered by Justice Breyer on May 4, 2009, the Court held that a prosecutor must be able to show that a defendant knew that the identification he used actually belonged to another person.
