The police were called to a domestic dispute. The wife told police that her husband was abusive and that he was a heavy cocaine user. The husband was present and denied the allegation. Police asked for permission to search the premises for drugs, which was consented to by the wife. The husband, however, refused to consent to the search. The police went ahead anyway and found drugs in the husband's belongings. After being arrested on drug charges, the husband filed a motion for suppression of the evidence based on lack of consent.
