Archival medical examiner specimens may contain perpetrator DNA evidence useful in unsolved ("cold case") homicides. The Office of the Chief Medical Examiner (OCME) histology slide archives were searched for sexual assault smears for all 376 female homicides from 1990 to 1999. Of these, the OCME had sexual assault smears on 84 of which 13 slides had sperm. Of these 13, six were still unsolved. DNA profiles were obtained on all six (5 from smears and one from swabs). Combined DNA Index System ( submission resulted in two matches ("hits") for new suspects. In addition, three suspects were eliminated in two cases. Our review of archival sexual assault smears resulted in DNA profiles that were able to assist in the investigation of four cold case homicide investigations. It may be worthwhile for medical examiner offices to search their archival histology slides for sexual assault smears on previously unsolved cases particularly those prior to the mid-1990s when DNA testing was less widely available.
法医存档标本可能包含对未侦破（“悬案”）杀人案有用的犯罪者DNA证据。对首席法医办公室（OCME）1990年至1999年期间376起女性杀人案的组织学切片档案进行了搜索，以查找性侵犯涂片。其中，OCME有84份性侵犯涂片，其中13张载玻片上有精子。在这13起案件中，有6起仍未侦破。对所有6起案件（5起来自涂片，1起来自拭子）进行了DNA分型。联合DNA索引系统（CODIS）比对结果显示，有两名新嫌疑人与之匹配（“命中”）。此外，在两起案件中排除了三名嫌疑人。我们对存档性侵犯涂片的审查得到的DNA分型能够协助调查四起悬案杀人案。法医办公室在其存档组织学切片中搜索以前未侦破案件（特别是20世纪90年代中期以前DNA检测不太普及的案件）的性侵犯涂片可能是值得的。
