I got the same email with the same story saying she's (Aril Dawkins) looking for a daycare provider for her 3 year old son "Brian". Sent me a picture of both of them. Then sent me a cheque for more than I asked for. Said it was sent by her colleague Sally E Oric. Asked me to send the remaining balance for her son's hospital bill.
I knew it was a scam right away and replied that she can pay me when we meet in person but I will not cash the cheque or send any payment to Mexico. After that reply she never wrote back. This is a scam and be aware.
