Summary

DNA testing on aborted fetal material can identify rape perpetrators. This forensic DNA analysis, using short tandem repeat (STR) profiles, can also help identify mothers from vernix caseosa, aiding paternity and maternity investigations.

Area of Science:

  • Forensic Science
  • Genetics
  • Obstetrics

Background:

  • Pregnancy resulting from sexual assault presents unique forensic challenges.
  • Establishing paternity in such cases can be crucial for legal proceedings.
  • Fetal tissues are potential sources of genetic material for DNA analysis.

Purpose of the Study:

  • To evaluate the feasibility of obtaining DNA-STR profiles from aborted fetal material.
  • To demonstrate the utility of fetal DNA analysis in identifying perpetrators of rape.
  • To explore alternative tissues, like vernix caseosa, for maternal DNA identification.

Main Methods:

  • DNA extraction and Short Tandem Repeat (STR) profiling were performed on aborted fetal tissues.
  • Analysis included four rape cases and two cases of infant abandonment.

  • Comparison of fetal DNA profiles with suspect and maternal samples.

    • Main Results:

    • Successful determination of DNA-STR profiles from aborted fetuses was achieved.
    • Fetal DNA analysis successfully linked perpetrators in rape cases.
    • Bloody vernix caseosa proved to be a viable source for identifying the putative mother.

    Conclusions:

    • DNA-STR profiling from aborted fetal material is a reliable forensic tool.
    • This method can provide critical evidence in sexual assault cases.
    • Vernix caseosa offers a valuable alternative for maternal DNA identification.
