Licensing — Driver’s license — Suspension — Evidence — Blood test — Blood draw at hospital, chain of custody of blood sample, and blood test results were fatally flawed where blood vial was not labeled with licensee’s name, date and time of collection, and initials of person who collected sample; chain of custody had gaps as to where blood vial was located and whether it was refrigerated; and description of blood vial by trooper who received it from hospital was inconsistent with that of analyst who tested blood — Finding that licensee was driving under influence was not supported by competent, substantial evidence — Certiorari granted
