No criminal charges will be filed in connection with a fatal school bus crash in southern New Jersey last year, prosecutors said Wednesday.

The crash occurred in February 2012 when a dump truck collided with the back of the bus and rammed it into a pole at an intersection in Chesterfield Township.

Isabelle Tezsla, 11, the daughter of a New Jersey State Police trooper, was killed in the crash, while both her triplet sisters and another student were seriously injured.

In announcing his decision Wednesday, Burlington County Prosecutor Robert Bernardi noted that a National Transportation Safety Board report on the crash identified factors that clearly demonstrated negligent conduct on the part of several parties.

Bernardi, however, said none of that conduct rose to a "level of recklessness" needed to bring criminal charges against anyone involved in the collision.
