You are examining evidence from an old crime scene. You have a blood sample, but you believe that the sample may be too degraded
to get DNA from. You decide to try to retrieve mtDNA from the sample and compare it to a sample from your suspect. What information could this sample give you?
This simple could give a close relative to the person, or to the EXACT person, then that is when investigators, checks alibis at the time of the incidence, or check footages in the Area to see if the person appeared on any (I know that they would probably get the footage the day it was called).
