Satterfield entered an open guilty plea to various offenses, including three counts of leaving the scene of an accident involving death or personal injury, 75 Pa.C.S. § 3742. Reasoning that Satterfield left the scene, leading to the deaths of three individuals, the trial court sentenced him on the three Section 3742 convictions to incarceration for consecutive terms of 3 to 6 years. The Superior Court affirmed. The Pennsylvania Supreme Court reversed. The Court ruled Satterfield raised a meritorious challenge to the legality of the sentences and concluded that two of Satterfield’s three sentences were illegal. The Court held “that the unit of prosecution for the crime of hit-and-run in Section 3742 is the act of leaving the scene of an accident without first rendering aid and providing information as required by Section 3744.” Therefore, two of the three sentences were illegal because Satterfield violated this criminal provision once.
