One (1) used latex condom

  • Item was swabbed internally and externally. The residue from the swabs dissolved in methylene chloride (organic) and water (aqueous).
    • The organic portion was analyzed by FT-IR revealing the presence of polydimethylsiloxane (PDMS) from the external swab.
    • The aqueous extract from the internal swab was analyzed for the presence of DNA. Insufficient quantities of DNA were found.
    • The aqueous extract from the external swab was analyzed for the presence of DNA and found to contain sufficient quantity and quality. The DNA was submitted for STR analysis.
  • Duplicate swabs were stored for future analysis if needed.
