:twocents: I previously read this post and as noted, delayed...hesitated...declined to reply as I thought it might be O/T but let's approach this as if it were a final examination test question rather than a real life situation.
:innocent: Firstly Bern, if this involves a member of your inner circle be she family or friend, my condolences of your loss, even all these years later.
Scientifically: The ONE clue in a completed sexual assault/rape is the evidence of seminal fluid, this is picked up by chemical testing at the scene and yes, the rain or any water/fluids present MAY dilute the fluids left but the test is a rather specific reaction. HOWEVER, the perp may have used a condom, not ejaculated or if ejaculated, may NOT HAVE LEFT spermatozoa for DNA testing. Given the guidelines of my jurisdiction, all body cavities would be evaluated as part of a sexual assault kit, what was done in that jurisdiction in 1993 is "up for grabs".
Absolutely fact that DNA test existed in 1993 BUT the database was small and the time frame to get results was LONG! There were few reasons to "get" samples of DNA unlike todays' rule of a felony conviction equals DNA donation and a lifelong registry! (On topic to Casey Anthony: they "got" hers!):floorlaugh:
Your question regarding the body condition is closer to the reasoning IMHO why if an assault occurred it could not be CONFIRMED. Without graphic details, the decomposition process can be accelerated by the insects upon the moist, usually protected by clothing body areas and again, if blood pooling occurs from ANY reason there is an increase in certain insect/animal activity. Standard methods of identifying suspect non-consensual/"brutal"/aggressive sexual (and in a 12 yr old, IMHO all terms APPLY!:banghead
activity is to visually observe the internal & external labia & mons area. Decomposition, slippage & bloat CAN obliterate a visual examination. While the date was February, I'm unsure what the environmental factors were that would/could influence the state of the body but traditionally COLD preserves and HEAT destroys biological evidence, inclusive of the body itself.
:sick: This is NOT an easy topic to discuss/explain or even share because what is screaming out from Bern's example is somebody's PAIN at not knowing what happened FOR SURE to a loved one, be it (he/she) a child or adult. :maddening: Rest assured that the efforts and achievements that this victim's life provided to ALL those involved in HER quest for "justice" made up the stepping stones that allow the SUCCESSFUL resolution and justice for another's family.........AND MAYBE EVEN STOPPED ANOTHER CRIME!
:twocents: N.B. The information I'm attempting to impart is based on the sketchy material presented above AND without hard-copy background data yet the experience of this being 2011 vs 1993 (years (gulp) I'm admitting I remember vividly!):seeya:
If I overstepped boundaries by answering Bern and LiveLaughLuv, mea culpa and mods:rocker:......do thy thing!:innocent:
