The Farmingdale School District Superintendent told News 12 Saturday night that all the students who were involved in the deadly bus crash on I-84 in Orange County are expected to recover.

Investigators say the crash left more than a dozen injured.

All students and adults were part of the school band.

Officials have identified the two adults killed in the crash as 43-year-old Gina Pellettiere, of Massapequa, and 77-year-old volunteer chaperone Beatrice Ferrari, of Farmingdale.

Earlier on Saturday, a Westchester Medical Center spokesperson told News 12 some of the victims who were treated for injuries were improving.

NTSB investigators continue to examine what exactly caused that crash.

The NTSB said it plans to remain at the scene of the crash for about a week during its investigation. Investigators will interview the victims and driver, as well as examine the bus mechanics.
