Those killed during the crash were Rockland residents Robert Deutsch, 42, and Shloma Binhack, 22, both of New Square, Howell said.
The crash took place when a 2009 Ford Econoline van, driven by Jean Tondreau, a 69-year-old resident from Hillcrest, left the roadway and struck a tree, police said.
The nine other occupants are still currently hospitalized with serious injuries, Howell added.
Several of the occupants had to be extricated by members of the Hillcrest Fire Company No. 1 and New City Fire Engine Co. No. 1.
All of the occupants were transported to either Nyack Hospital or Westchester Medical Center.
