Deerfield Police Department, Massachusetts: SCAM ALERT: This afternoon we were alerted by the Bement school that someone is sending out express mail with letters and checks referencing a fund raiser for the school. THIS is a SCAM. Most of the letters have been in the Colorado area, the checks have Greenfield Cooperative Bank on them. If you receive one please let us know, or through them away. They may also have a connection to a Craigs list ad.
