Robert F. Bukaty / AP A makeshift memorial with crosses for the victims of the Sandy Hook massacre stands outside a home in Newtown, Conn., Dec. 14, 2013.

A co-founder of a Tennessee-based charity to support the victims of the Sandy Hook Elementary School shooting told the Associated Press that she cannot account for more than $70,000.

Ryan Graney, who created the 26.4.26 Foundation along with Robbie Bruce, said the group collected $103,000 but only distributed $30,000, to a non-profit youth sports center in the city of Newtown, Conn. where the shooting happened in Dec. 2012. Graney said she filed a report with the FBI and local authorities.

The group first announced on its Facebook page last month that it was missing the funds.

“We are saddened to see this great movement come to such a crumbling and embarrassing end,” reads the post. “We fought so hard to do good and in the end 26.4.26 was taken advantage of and for that we are sorry.”

The AP could not reach Bruce, an endurance runner, for comment.
