DATING SCAMMER Mary Joe

Hello,
I have to report a scammer.
Her name is Mary Joe, she contact me through a yahoo e-mail because she gave me her mail in whoisnear.
She was working in a school ( IDC Primary School 69 Odo Ona Elewe Asipa, Oyo, Ibadan, Nigeria) for orphans in Ibadan Nigeria . She went in Ibadan with her parents in 2010, but her parents had a car crash and burned in their car. She never worked in Nigeria as she cant work there because she''s british.
I talked to her through yahoo messenger but also on the phone 3-4 times.
She lived with a woman who have a a little food store (a good samaritan she said called Alabi Olabode) near the school were she work as a volunteer.
Since 2010 were shes supposed to be caught in Nigeria because she have no money.
I sent her money for a flight ticket ( in a transfer to the account of her boss :
FAMAKINWA OLADAYO BAMISE
Details of the transfer :
BENEFICIARY BANK: SKYE BANK PLC, LAGOS
Bank Address: adeola hopewell lagos Nigeria
SWIFT CODE: PRDTNGLA
BENEFICIARY NAME: FAMAKINWA OLADAYO BAMISE
BENEFICIARY A/C NR: 2042520000054
No 14 Olorunfemi Street Lagos Nigeria

but later she said she would need some test before she can''t leave Nigeria for *** Test, tiphoid test, Ebola V test, Malaria test, tuberculosis test) and that it cost 4000 pounds !!!
I became suspicious and checked with Us and Canada embassy in Lagos Nigeria to know if these tests are really needed when you''re leaving Nigeria after living there for a long time , and if they can cost as much as 4000 pounds !
I also ask yahoo question were they said it was a scam. The Embassy said they never heard of theses tests and that it was probably a scam.
When i confront her with the results of my research she said i should trust her and that i should not let anybody stand between us.
As i was convince she was a scammers (after talking to others peoples who had been scamed in scam of the heart) i blocked her mail and messenger in yahoo).
it happens between january and july 2012 !
