The arrest comes a day after police found two bodies in the Elmont home. Police were called after one of the victims, 30-year-old Guerby Ormejuste, failed to report to his job as a New York City correction officer.
Also found dead in the house was 65-year-old Bob Ormejuste.
Police are also searching for his wife, Rose Ormejuste, as well as a 1998 Lexus that had been in the driveway.
