The Marshalltown Police Department has issued a media release to inform residence of an scam recently showing up in that city.  Scammers are using rental listings on Craigslist to entice people to send money to them while stating they will send you the keys for the property.  These properties are not for rent and no keys are ever sent.  If you feel you are a victim of a fraud, you are urged to contact the police department as soon as possible.
