As part of the IMPACT Film Festival in Philadelphia during the Democratic National Convention tomorrow, the documentary "Newtown" will be screened.  The documentary, which focuses on the aftermath of the shooting at Sandy Hook School, follows victims' families, first responders, teachers, neighbors and clergy. 

David Wheeler and Mark Barden, whose first-graders were among the 26 children and educators killed in December 2012, said they wanted people to understand the grief in Newtown and to open up some lines of communication among those affected by the tragedy. 

Among other things, the film shows the struggle of an emergency medical technician who transported Ben Wheeler to the hospital and wrote a letter to his family. It explores the emotions of a priest who had to preside over numerous funerals and of teachers feeling guilty about not wanting to go back to work. 

"Newtown" is scheduled for a wider theatrical release in September and will later be broadcast on PBS. 

A post-screening panel will feature film director Kim Snyder, producer Maria Cuomo Cole, Mark Barden and Congressman Ted Lieu.
