Investigators with the Better Business Bureau are warning about possible scams in the wake of the tornado in Harrisburg.  Bill Smith says scam artists are likely to use the tragedy as an opportunity to take advantage of people's generosity.

Smith says no particular threats have been identified but it's a good thing to be suspicious.  He says you should beware of groups using names similar to large, well respected organizations.  Do not give cash, and don't ever give your credit card number to a fundraiser over the phone.  If you pay by check, you should use the full name of the organization and not make the contribution out to the fundraiser.
