-its not the second one-

having a backlog of untested DNA samples

Explanation:

Often, there will be lots of samples collected for DNA at a crime scene. This is to try and get a DNA sample from something, because we cannot be sure what will or will not have DNA.

Remember, DNA testing has been around for a relatively short time - it has only been used routinely in the last 20 years or so. Even in this short time, it has had a lot of success.

That means that everyone analyzing a crime scene will be collecting samples to be DNA tested. This huge demand for the services (which is increasing every year) means there is a huge backlog of DNA samples that labs cannot keep up with.
