21 News spotted at least two Valley billboards with a message reading "Dayton Strong" after Sunday's mass shooting there.

One of the billboards is in Austintown outside of the Giant Eagle on Mahoning Avenue, and another is on Market Street in Youngstown.

The billboards promote The Dayton Foundation, a fundraiser set up to help those impacted by the shooting, which left nine dead and others injured.

Ohio Macy's have also stepped up to help, allowing customers to round up their purchases starting on Wednesday to help support the fundraiser.
