COLUMBIA, Mo. -

After finding $2500 at the Glen Carbon, Illinois store, MERS (Metro Employment and Rehabilitation Service)/Goodwill is looking to find the donor they believe may have accidentally placed money in with their item donation at the Columbia store.

An employee found $500 cash inside an envelope while filtering through donations on Monday.

Goodwill's loss prevention team believe the donation was made on Tuesday, March 11 between 9 a.m. and noon.

Goodwill recommends looking in pockets, bags, envelopes, and small boxes so you don't accidentally let go of something you didn't intend to.

“It seems like we are seeing this sort of accidental donation occur more and more, particularly around the spring," said Lewis C. Chartock, Ph.D., President and CEO of MERS Goodwill.

The donor is encouraged to contact Goodwill at (314) 982-8802.

If no one comes forward, the money found will go to MERS Missouri Goodwill’s programs that help the community.
