Drawn by claims of a “rock solid investment” and “guaranteed” interest of 9.25 percent, Joseph Hamel, 90, and his 85-year-old wife, Winifred, invested their $45,000 life’s savings in U.S. Capital Funding of Lake Worth, Fla. in September.

The interest checks of $455 arrived every month until January, when the check was for only $68.
