Sadly there is not way to deal with a stalker that is effective. Any contact you have only encourages them. You can get a restraining order but in some cases even that makes the stalker think you want their attention even more. I did read a study once that in some cases civil litigation was fairly successful. Obviously you would have to have tedious documentation of monetary and emotional damage over time. No one likes to be hit in the pocketbook. But even that wasn't effective in ALL cases. Prison seems like a good idea.....
