This man calls up (after researching YOUR local-area fund-raising groups), pretends to BE from that fund-raising group, and asks you to write a check in support of [said fund]. He then says to leave it on your door..."someone will be driving by to pick up the check within the next day".
He will even go as far as asking you to put "for deposit only" on the back of the check. What this man does is simply open up a bank account in the name of your local [said fund], so he can quickly deposit your checks and gather your money. Just as quickly, this man will close this account and your money is, *poof*, gone and stolen. Cannot be recovered.
He is NOT registered for fund raising with the Attorney General of Massachusetts.
