“Just give us our stuff, please! Just give it back!” cried LaWanda Hawkins of Justice for Murdered Children. “How dare you take the pictures and stuff? Do you know what that did to us?” she asked angrily.

Those items in the stolen truck include photos and shoes of murdered children, along with brochures, banners, buttons and other supplies the group had compiled for a weekend fundraiser. They are worth next to nothing monetarily but are priceless to the families who donated them.

“They’re little baby shoes, 3- or 4-month-old babies. We wrote little notes. They might have drew a little pictures. We want those back,” Hawkins pleaded.
