This is a guide on how to get all the collectibles in Battlefield Hardline.
There are a total of 71 collectible pieces of evidence, and 21 warrants to serve to suspects. You will need to find all the evidence to then be able to collect all the case files.
On the side, if you get all the collectibles, you will get these trophies and achievements.

You have a scanner that you can use to find evidence collectibles. It will buzz when one such collectible is nearby. It will also highlight said evidence when you aim at it, and it can tag suspects who have outstanding warrants. When you equip the scanner, you will get information on how many pieces of evidence are found in the current location. There will even be an arrow that points the direction you will find the closest evidence.
Now here’s the good part. You don’t have to find evidence again, in case you find it. When you find all the evidence in an area, you can quit that area without going to the checkpoint, and the game will autosave that you found all of it.
Finally, when you complete a case file by collecting all the evidence in an area, you unlock new weapons and equipment.
