Well, I'm not telling you how to live your life, but someone who used to work in a related field, please at least consider it if you ever are in that situation. It's always useful to have more data, and some data will always come from random findings like this.
Maybe AI image recognition is good enough by then to actually determine if it is from a human or some other animal, so that you know beforehand that your paperwork will not be in vain at least. I don't expect that there will be much of a police investigation, the age should be rather obvious in most cases. On the other hand I've heard that there are states where the police get less than half a year of training, so maybe there will be one. But still, think of the potential scientific value :)
