Dirty Bomb Materials Found 

The materials were found during the investigation of the shooting of James Cummings.

Four one-gallon containers were found, all containing a chemical mixture.

There was also literature in the house about how to make a &quot:dirty bomb&quot:.

The FBI reports that Cummings may have been linked to white supremacist groups.

Authorities did not release information about the substances. Much of what is known was gained through a document that was leaked.

Belfast police Chief Jeffrey Trafton says local citizens were never in any danger from the chemicals found.

The investigation into the shooting is open and on-going. At this this time, Amber Cummings has not been charged with anything.

State police are handling the case.
