Volunteers at the AARP Foundation Fraud Fighter Call Center in Denver work to warn Colorado residents about investment scams targeting older people. The 88-year-old volunteer Joe Pells calls people to inform them about common fraud tactics like promising high returns and creating a false sense of urgency. The AARP Foundation and Colorado Attorney General's Office also operate fraud prevention programs that take complaints and provide resources to help people avoid scams. These programs help many victims each year but financial fraudsters still disproportionately target older, wealthy individuals who may be more vulnerable to fraudulent pitches.
