If you want to know more about this horrible little scammer you could always hire a Private Investigator. There are lots of them in Mykolaiv. Some will even tell you if it is possible to prosecute her for compensation. Most P.I's are ex KGB. SBU. Police, Military Investigators etc. Fees can be from as little as $25 per day. Depending on what your requirements are. The ones i have used in the past were very reasonable, reliable with a prompt response. Well worth a try as prices are agreed before any work is done and there are NO hidden charges.
As soon as Ukraine joins the European Union. You will be able to use the courts there to get this scammer some jail time.
