In Collins v. Superior Court, 158 Ariz. 145, 761 P.2d 1049 (1988), a person suspected of driving under the influence refused to submit to a breath test, but no blood was drawn for medical purposes. The police then obtained a search warrant and, pursuant to the warrant, a blood sample. Id. at 146, 761 P.2d at 1050. Because the blood was not obtained for medical purposes, however, the court held that the evidence must be suppressed. 158 Ariz. at 146-147, 761 P.2d at 1050-1051.
