Five mysterious letters received by the Kansas Department of Social and Rehabilitation Services in Wichita were straightforward.

Each contained a handwritten request: "Please use for prescriptions for the poor." And inside each envelope received more than a year ago, stunned social services workers found ten $100 bills.

Wichita SRS spokeswoman Laine Hash said "It kind of knocked our socks off" to unexpectedly receive an anonymous cash donation.

After months of consideration, SRS officials went to Medical Service Bureau, a Wichita nonprofit that helps the needy get prescriptions.

The organization recently submitted its final report: 252 prescriptions went to 128 unduplicated clients who were uninsured and unemployed.
