I've received at least half a dozen messages almost exactly like this.  It's a scam.

Birders beware of the email from Margaret Bragg.   Unless you know her personally, this email is suggestive of a frequently used strategy to defraud unsuspecting and kind people.

I'm writing this with tears in my eyes,my family and I came down here to London, United Kingdom for a short vacation.unfortunately,we were mugged at the park of the hotel where we stayed,all cash and credit card were stolen off us but luckily for us we still have our passports with us.

We've been to the Embassy and the Police here but they're not helping issues at all and our flight leaves in few hours from now but we're having problems settling the hotel bills and the hotel manager won't let us leave until we settle the bills. Well I really need your financially assistance..Please, let me know if you can help us out?

   Am freaked out at the moment!!
