Stacey Schwerin says she wasn't looking for cash when she held a sign asking drivers to get tested last week along a street in Bay City, about 100 miles northwest of Detroit.
Schwerin says she just wants to help her daughter, Jessica, who was diagnosed last month with chronic kidney failure.
Jessica is on Michigan's organ donor registry. She's also facing dialysis treatments that pose significant geographic and financial challenges for her family.
Her mother tells MLiv.com that several people have offered money, but she turned them down. She just wants to find a donor.
She says she can't be a donor because of health problems.
