I’m a Forensic Files and nerd and have noticed that DNA does not seem to have a standard turnaround time? Going from the late 90s to today, there seems to be a very arbitrary amount of days/months/sometimes years that must go by before the DNA is processed? Not to identify the bad guy, but just to get the profile isolated.
I understand available resources, and the urgency of the case play a role, but there doesn’t seem to be anywhere near standard amounts of time established to get information back? Why is the time variance so widely distributed?
