In Serrano v. Pennsylvania State Police, 130 Pa. Commw. 531, 568 A.2d 1006 (Pa. Cmwlth. 1990), a criminal defendant was imprisoned for four months because a regional crime lab failed to timely test a packet of white powder that turned out to be aspirin rather than heroin. The Court rejected the argument that Section 8522(b)(3) applied, stating that the packet did not cause the injury but rather the lethargy in conducting the chemical analysis.
