The American Red Cross opened a shelter at nearby Edgewood Elementary School. A small room at the school quickly filled with donations from the community. The Red Cross has stopped accepting donations for now because it's received an overwhelming amount of clothes and items for victims of the fire.
The church next door has stepped in to help, but it is not certain how much it can handle donations wise. The Red Cross reminds people they can also simply donate cash.
