They gave his remains to Broadway.

Family and friends of slain Portuguese journalist Carlos Castro honored the dead man’s wishes yesterday by pouring his ashes down a subway grate in Times Square.

A funeral was held in Newark yesterday for Castro, 65, who was allegedly castrated with a corkscrew by his 20-year-old lover, male model Renato Seabra, on Jan. 7 in a room at the InterContinental Hotel in Times Square.

After the service, his sisters and a friend took a limo to Broadway and 43rd Street and quickly dumped his ashes without saying a word, said photographer Leandro Badalotti.

It wasn’t immediately clear if the family had authorization to dispose of his remains in public.
