Daniel Sikkema has been sentenced to life in federal prison for orchestrating the brutal murder-for-hire of his estranged husband, prominent New York art dealer Brent Sikkema. The sentence was announced today, November 4, by the United States Attorney’s Office for the Southern District of New York alongside the Federal Bureau of Investigation (FBI), bringing a definitive, legal conclusion to a high-profile case that sent shockwaves through the international art world and the bustling gallery districts of Manhattan.
The 56-year-old defendant learned his fate following a rigorous legal proceeding that exposed a chilling conspiracy driven by greed and marital discord. In addition to the mandatory life term behind bars, Daniel Sikkema was handed a consecutive sentence of five years of supervised release. The judgment reflects the severity of a crime that federal prosecutors described as thoroughly premeditated and executed with a total disregard for human life.
The tragic sequence of events began to unfold in January 2024, when Brent Sikkema, the esteemed 75-year-old co-owner of the renowned Manhattan gallery Sikkema Jenkins & Company, was discovered dead in his residence in Rio de Janeiro, Brazil. Brazilian authorities responding to the scene found that the veteran art gallerist had been violently stabbed 18 times in what appeared at first to be a targeted and vicious assault. The unexpected loss of a foundational figure in contemporary New York art circles immediately reverberated globally, drawing intense media scrutiny and launching an international investigation that ultimately crossed borders to connect the homicide back to the United States.
Just two months after the shocking discovery in South America, law enforcement agents arrested Daniel Sikkema in Manhattan. The initial arrest was centered on charges of passport fraud, but the scope of the federal investigation quickly widened. As federal prosecutors and the FBI unraveled the financial and digital trails connecting New York to Brazil, Daniel Sikkema was hit with additional, graver charges: murder-for-hire, conspiracy to commit murder-for-hire, and conspiracy to murder a person in a foreign country. The case moved swiftly through the federal court system, culminating in a dramatic two-week trial in May where a federal jury reviewed the evidence, listened to witness testimonies, and ultimately found him guilty on all counts.
The gravity of the sentencing was underscored by US Attorney Jamie McDonald, who issued a stern statement following the court proceedings. "Today’s life sentence holds Daniel Sikkema accountable for a cold, calculated murder-for-hire plot that resulted in the murder of his husband, Brent Sikkema," McDonald declared in an official press release issued by the Department of Justice. The prosecution emphasized the manipulative and calculated nature of the defendant’s actions as the couple’s divorce proceedings grew increasingly contentious.
"For months, the defendant manipulated friends, family, and employees to execute a killing driven by greed. His actions demonstrated a profound disregard for human life and the rule of law," McDonald continued, highlighting the psychological manipulation that underpinned the conspiracy.
According to court documents and federal investigators, Daniel Sikkema had enlisted the services of Alejandro Prevez, who had previously worked as a security guard for the couple. As legal disputes surrounding their divorce dragged on, Daniel Sikkema arranged to pay Prevez to travel and carry out the fatal assault against his husband. The paper trail established during the federal trial revealed that shortly after the violent stabbing took place in Rio de Janeiro, Daniel Sikkema transferred an initial payment of $5,000 to Prevez, accompanying the funds with promises of substantial future payments once the plot was successfully concluded.
The apprehension of the alleged triggerman followed swiftly after the crime was uncovered. Brazilian law enforcement agencies tracked and arrested Prevez just four days after Brent Sikkema’s body was discovered. According to the United States Attorney’s Office press release, Prevez remains in custody as he awaits formal charges and prosecution within the Brazilian court system, where separate legal proceedings will address his direct participation in the homicide.
The loss of Brent Sikkema deeply impacted the contemporary art community, where he was widely regarded as a visionary gallerist and a dedicated champion of groundbreaking artists. In the early 1990s, Brent Sikkema co-founded the institution—initially established as the Sikkema Jenkins Gallery and later known as Sikkema Malloy Jenkins—alongside his business partner, Michael Jenkins. Over three decades, the Manhattan gallery established itself as a premier destination for adventurous and culturally significant contemporary art, showcasing the work of globally acclaimed creative voices.
Throughout his distinguished career, Brent Sikkema curated exhibitions and represented a stellar roster of visual artists, including luminaries such as Kara Walker, Sheila Hicks, and Vik Muniz. Today, the gallery continues to represent more than 30 prominent artists, maintaining a cultural footprint in New York City that endures despite the tragic circumstances surrounding its co-founder’s passing. With today’s sentencing of Daniel Sikkema, the federal chapter of the judicial process has reached its conclusion, sealing a lifetime behind bars for a crime born out of betrayal and financial avarice.
