Reporting an email hacker beyond local authorities?

My X-Girlfriend whom I have been living apart from since Oct 10' took it upon herself to hack into my email account for several days. She identifed various emails that I had been corresponded with a new aquintance ( woman ). What follows next is unbelieveable: She contacted the woman via here business sell phone to talk with woman who quit frankly was utterly shocked that she called her at 2AM in the morning, printed our email conversations made copies of them and went ( walked - seen on security cameras ) into the woman's executive office, meet with an unidentified person within Baxter International to took the illegally obtained emails, called the sister division HR Mngr. at BCU. This unidentified person at Baxter told BCU HR to have this woman repremanded - keeping in mind that none of emails where from a place of business computer devices. They were all personal computer generated messages. The X then used information obtian through the illegally obtained ( hacked ) infomation to track down the new woman's home which is 20 mins. as way in a completely seperate city and conducted several drive-bys ( stalking of her residence ) by obtaining her address through my personal e-mail account. Following this an another incident of illegal entry into my condo unit commons area not my condo, endless emails, phone calls all using her company blackberry, IPad and computer I decided to report the incidence to the local city municipal authorities who took down the information in a crime report. I handed them several of the emails that my new aquaintence forwarded to my attention as proof that the X had been into my emails and used them to directly contat the new aquaintenc. The authorities contact the XGF via phone asker about the incidents which she flately denied although they ( the authorities had evidence of the IP Address used, user name of the @yahoo.com site and other rlelated materials. The local authorities later contacted me and advised they were leaving this matter as a domestic and that no action was going to be taken. Keeping in mind that my X and I have been seperated since Oct 10' and live in completely seperate homes. Based on my filing a police report of the incident described above, the XGF then when to the county court house to obtain a OP against me stating the basis of this OP was directly because "I reported a false crime" to the authorities". Keep in mind that I gave the officers the emails IP addy etc. My question: althought the local authorities will not or cannot take criminal investigation of this matter, can I report this matter up to a higher level were I believe it needs to be. I mean come on, this woman hacked a personal email account, used the materials to get an employee repremanded and walks away scott free and obtains an Order of Protection because of her actions - is this the type of society we have become - commit a crime, get people nearly fired because of vengence and no one will take criminal actions against this person? Really
