Of course, there is a vast gulf between what might legally be considered stalking and what might result in a criminal prosecution.

Being on the investigation side, and going just on what the poster has written here, I do not see most agencies or prosecutors offices I know of moving on this to any great extent. Perhaps if the OP lived here or had been subject to more direct threats, but as of right now I see a couple of misdemeanors and a weak felony that would be quite expensive to pursue. Police and DAs have to cull the herd, so to speak, and pursuing cases that are not likely to go to court or not likely to result in a conviction are not going to be pursued.

If, to make the case, the state would have to call in a number of witnesses with alphabet soup after their name, the DA is not likely to go with it. It will be just too expensive.

It is a sad but true fact of life that the criminal justice has only limited resources and not all offenses can be pursued to their full potential.

Now, if the OP wants to pursue a civil case, and the defendant has the means to pay off an award, then the OP can pursue this angle. A civil case will, of course, be expensive, but will only require proof by a preponderance of the evidence and not proof beyond a reasonable doubt.
