Daniel Sikkema, 55, was convicted in federal court in Manhattan for orchestrating the murder of his estranged husband, art dealer Brent Sikkema. Brent Sikkema, 75, was found fatally stabbed in his Rio de Janeiro townhouse in January 2024. Daniel Sikkema faces a mandatory life sentence for the murder-for-hire conspiracy, which resulted in death.
