Abstract:
In addition to obtaining DNA-STR typing of an evidentiary stain for individual identification and paternity tests, knowing the time since deposition (TSD) is also highly desired in forensics. To provide a reference for the research of predicting the TSD, this article reviews the reported optical, cell biological and molecular biological methods of determining the age of bloodstains domestic and overseas, and also introduces the application of microbial forensics, a new field of forensic science, to provide space-time clues of evidentiary stains.
