I am going to be brutal here. I COULD be wrong. However, I have quite extensive experience of this.
His profile sounds just like your classic "romance scammer". They are generally from Europe or the US; generally working in Africa or Asia; generally an "engineer" - covers a multitude of sins; generally widowed or divorced (wife having been caught in bed with best friend) and often have one child.
The pictures they use are generally stolen from internet model sites. They sound convincing - heck they ARE convincing. My own sister in law fell in love with a scammer.
You could do no worse than to track his email address. Or you could log into romancescam.com and see if his profile/email address flag up? If it was a free dating site the chances of it being a scammer increase exponentially. You could also create a fake email account and start emailing him under an assumed name to see if you get a response. If it is a free dating site, create another profile and email him.
My guess is that when it comes to the first meeting, his wallet will be stolen and he will ask you to pay for his flight/hotel etc etc.
Until a couple of years ago, I used to bait these guys just for the sheer hell of it. I still play with the odd one now and again. It just sounds dodgy. Any presents will be bought on a stolen credit card and as has already been suggested, in order to get your confidence.
I repeat, however, I COULD BE WRONG. If I am wrong, I wish you the best of luck.
