Problem: You have just obtained an item of evidence from the evidence locker. The brown paper package with intact evidence seals appears soggy at one end and there is a strong odor associated with it. On opening the evidence bag you see what appears to be a blood soaked item of clothing that has been wrapped in an unsealed plastic bag while still wet. The item is heavily stained and infested with maggots. From a biological standpoint, what effect would the inappropriate packaging described in #1 have on the following tests
a). Kastle-Meyer presumptive test
b). Biochemical marker identification
c). Species tests
