KANSAS CITY (KCTV/CNN) - Well-wishers from around the world are sending donations to a homeless man in Kansas City after learning about the good deed he did for a young woman.

It all started afterSarah Darling accidentally dropped her diamond engagement ring into Billy Ray Harris' donation cup.

When she realized it the next day, she returned to the place that Harris had been the day before.

He had been keeping the ring safe for her and gave it back.

Darling was so happy that she set up an online fundraising site for Harris that has raised over $140,000 as of Monday February 25.

The money will be given to Harris at the end of a 90-day collection campaign.
