Dinah Tatman is a pastor from nearby Bellafontaine. She comforted residents of an area targeted by looters.

"If nothing else, you have that one or two you try to encourage, to plant a see that what you're doing is wrong," Tatman said. "I had a young man tell me after we dialogued, with his hands full of merchandise.
"When I turned to walk away he said 'ma'am, I'm sorry.' "
