Pennsylvania DUI law can often be nuanced and complex, as a recent case illustrates. In December 2014, K.W. was involved in an accident in Cameron County in which her car struck two pedestrians. One of the pedestrians sustained serious injuries, and the other was pronounced dead at the scene. When police arrived, Trooper J.R. asked K.W. to perform a field sobriety test, which she performed poorly. K.W. then submitted to a portable breath test, after which she was placed under arrest on suspicion of DUI.
The police transported K.W. to the hospital for a blood test. There, Trooper J.R. read K.W. the O’Connell and implied consent warnings, as contained on the Pennsylvania State Police DL-26 form, after which K.W. consented to a BAC test. K.W. was subsequently charged with the following: homicide by vehicle while DUI; aggravated assault by vehicle while DUI; DUI of alcohol or controlled substance; DUI of alcohol or controlled substance with a BAC of .178%; DUI of alcohol or controlled substance; and careless driving.
Prior to trial, K.W. filed a motion to suppress the results of the BAC test based on Birchfield v. North Dakota. In August 2016, following a suppression hearing, the suppression court granted K.W.’s motion, and suppressed all evidence from the BAC test. The Commonwealth appealed, raising the following issue for review: “Did the trial court err in suppressing the results of the testing of [K.W.’s] blood, after a fatal, suspected DUI motor vehicle accident, on the basis of the United States Supreme Court’s decision in Birchfield v. North Dakota?”
