i said: Sent him a link to this page
He Said :okay but i would to come pick it up my self and hand you the cash but i am currently out of town for work,i work in an oil rig if you dont have an account you can simply get one for free at www.paypal.com its very easy safe and secure just few steps away and you get your cash... just lemme know okay?

I have had this number call me the guy says his name is Mark Taylor. We have been talking on Facebook for a while. Told me he was originally in YEMEN helping treat the wounded and injured. Now he wants me to help him supposibily to get back to the States. He says he lives in Lexington, NC. He has even sent me pictures of two kids that is supposed to be his daughter and son. I have not currently done anything to help him. But, now that I know that this is a scam I am going to quit talking to him.
