State v. Chastain

In State v. Chastain, 594 P.2d 458, 461 (Wyo. 1979), the Court upheld the exclusion of a blood sample from Chastain's "trial for DWUI" where: (1) the State conceded that the defendant "was not under arrest and, therefore, the blood-alcohol test would not be admissible for that reason alone;" (2) the officer did not "come close" to fulfilling the implied consent statute's requirements prior to obtaining the blood sample; (3) the blood sample was obtained "solely in the context of DWUI" and "no other charges were contemplated against the defendant (e.g., no mention of careless driving, no facts to support a greater charge than DWUI, such as vehicular homicide)."
