State v. Butler
In State v. Butler, 232 Ariz. 84, 302 P.3d 609 (2013), the defendant consented to a blood test after being advised of the consequences of refusal under the implied consent statute, but other factors -- specifically, the defendant's age, his mental state, and the duration and circumstances of his detention -- supported a finding that the consent was involuntary. 232 Ariz. at 88-89,20-21.
Butler therefore affirmed the trial court's suppression of the test results. Id. at 89,21.
