Luis Moreaux, a suspect in a cold homicide case, had a seemingly benign interaction with police over a missing registration sticker. He cooperated with the officers, even going into the precinct for questioning and licking an envelope at the officers' request.

The police, however, used the ruse of a missing registration sticker to obtain the defendant's DNA in an attempt to match DNA found under the victim's fingernails. Even though he was brought in under fallacious circumstances, the police still read the defendant his Miranda rights and he acknowledged that he understood them.
