Dried seminal stains from clothing are preserved in how much percentage of formalin |
|
Answer» Answer: Blood is a COMMON type of evidence and this evidence should never receive exposure to intense HEAT or humidity. In fact, it should be refrigerated until it is brought to a crime laboratory. Blood might be lifted by tape or it might be scraped and then preserved on a cotton square. Blood can ALSO be absorbed onto threads. Evidence items that are bloodstained may be packaged into a bag or envelope to prevent contamination with ANOTHER piece of criminal evidence or SURROUNDING objects. |
