On Monday, funerals were held in Floral Park for 19-year-old Paige Malone and her 22-year-old sister Jamie.
The sisters and 22-year-old Michael Mulhall were killed last Thursday when their car lost control and hit a tree along the Meadowbrook Parkway in Roosevelt.
They were on their way to a camp for the disabled in Hempstead, where they worked as counselors.
Two others in the car survived.
The cause of the crash is under investigation.
