Riker's body lay in state at the Governor's Room of New York's City Hall and on June 10 his body, along with that of Colonel James Miller of the 81st Pennsylvania who had been killed in the same battle, was escorted by the New York State Militia (specifically the Fifth Regiment, a battalion of the Fifty-fifth Regiment, a troop of horse, a troop of Lancers and the Harlem Chasseurs), to Green-wood Cemetery, Brooklyn, where Riker's body was placed in a temporary vault while it awaited permanent interment.
