To get you started, know the skills you should have:
Diligence
There are online criminal investigation courses, so accessibility of information is not a problem. However, you do need to be diligent to learn the craft. It will not be enough to read through the suggested materials without taking in everything. You should also take the initiative to go beyond what is expected and ask questions when you are confused.
Presence of Mind
You will see details of a crime that are not released publicly, and some of them might be too much if you have a weak stomach. If you want to be in this kind of profession, you need to learn to keep your cool. Presence of mind is also important when you’re looking at an unfolding crime scene, and you need to take in as much of the details as possible. This is something you can start honing early on because it can be handy in real life too.
Attention to Detail
This goes well with having presence of mind because when you have a clear focus, you can see everything more clearly. It’s important to stay objective on the job; otherwise, certain details might trigger you and cause a bias in your perception. You should also be mindful of seeing one case after the other, as you could mix up important information and ruin the case.
