More charges are pending against one of four police officers charged with conspiring to violate and violating civil rights, and more “overt acts” of three of the four officers originally charged are included in a superseding indictment that came down Tuesday.

The new charges came days after Sgt. John Miller pleaded guilty Friday to depriving an individual of his right to be free from the use of excessive force by a law enforcement officer and agreed to cooperate with the FBI. Miller could avoid jail time. The original indictment said the other three officers, Jason Zullo, David Cari and Dennis Spaulding, were known as “Miller’s Boys.”
