6. First Testimony  Testimony that a piece of evidence is what is introduced to be  Example: If evidence is introduced as defendant’s blood, there needs to be testimony that acknowledges that the evidence is in fact defendant’s blood

7. Second Testimony  Testimony of continuous possession by each individual who had possession of the evidence  Each person that handled evidence needs to testify  Each person that has handled evidence normally signs the package to track where the evidence has been
