Abstract
The screening of autopsy specimens, vaginal, buccal, and rectal swabs, for the presence of seminal fluid in rape homicide investigations utilizing classical techniques can lead to erroneous results. In the absence of spermatozoa, techniques are needed which can help to identify seminal fluid. This report illustrates the use of a multi-enzyme electrophoretic approach identifying seminal acid phosphatase (SAP) and lactic acid dehydrogenase (LDH-X) as an initial screening procedure. Subsequent analyses for the presence of acid and alkaline phosphatase (semiquantitative) yield information which can help identify false-positive SAP's. Additionally, salivary amylase can be tentatively identified using the same multi-enzyme procedure which informs the investigator of possible salivary contamination of the sample and possible erroneous PGM results. Statistics utilizing the multi-enzyme approach in case work are also presented.
