Jeffrey Ahn was a student at Trinity High School on the Upper West Side, where there is now a memorial for him.
Police say Ahn was walking to his parents' home in Amagansett when he was struck by a taxi.
Ahn's father says that he could have called for a ride instead of walking, but that he wasn't the type of person who wanted to burden anyone.
Police haven't said whether charges will be filed against the driver, 25-year-old Ladislav Smigura, who called police and stayed at the scene.
