Brent Sikkema was a pioneering New York art dealer who made his name by championing underrepresented artists and building an international clientele. Born in Morrison, Illinois in 1948, he studied photography at the San Francisco Art Institute and opened Wooster Gardens in SoHo in the early 1990s. By the time he co‑founded Sikkema Jenkins & Co., he was a fixture in the Chelsea gallery scene, known for his eye for emerging talent and his willingness to show women and artists of color.
Sikkema’s personal life attracted less attention until late 2023, when a bitter divorce and allegations of infidelity and financial exploitation surfaced. In January 2024 he was found brutally stabbed in his Rio de Janeiro holiday home, and authorities in Brazil and the United States later alleged that his estranged husband, Daniel Sikkema (also known as Daniel Garcia Carrera), had hired an ex‑security guard to kill him. The story shocked the art world and exposed a complex web of marital strife, legal wrangling, and international criminal investigation. In May 2026, a federal jury in Manhattan convicted Daniel Sikkema of murder‑for‑hire. The following sections outline what happened, the key evidence, legal proceedings, possible motives and the public reaction.
The Incident
On 14 January 2024, neighbors in the leafy Jardim Botânico district of Rio de Janeiro discovered Brent Sikkema, 75, lying lifeless in his home. He had been stabbed 18 times, and $40,000 in cash was missing. His Brazilian retreat was his sanctuary; he had told friends he wanted his ashes scattered there. At first, police suspected a robbery, but the ferocity of the attack and the precision with which the murderer entered the secure property suggested a more personal motive.
Investigators quickly focused on Alejandro Triana Prevez, a 30‑year‑old Cuban man who had previously worked as a security guard for the Sikkemas. Surveillance footage placed him near the house on the day of the murder. When Brazilian police arrested him at a gas station two days later, he allegedly confessed, telling officers he had been promised $200,000 by Daniel Sikkema to carry out the killing — though prosecutors later established that roughly $9,000 was actually transferred.
Search and Key Evidence
This case did not involve a frantic 911 search, but investigators pieced together a timeline through digital footprints and witness testimony. Key evidence includes:
Money Transfers
Prosecutors allege that in the months leading up to the murder, Daniel Sikkema wired approximately $9,000 to Prevez through intermediaries. Records show incremental payments from mid‑2023 until January 2024. The defense argued the payments were for work Prevez had performed for the couple in Cuba.
The December Attempt
In a written confession, Prevez said he first attempted to kill Sikkema on 11 December 2023. He used a key provided by Daniel to enter the house but abandoned the plan when he could not lure Sikkema from his locked bedroom.
Communication Logs
Prevez told police that after the failed December attempt, Daniel urged him to “finish the job.” Phone records show calls between the men on the days surrounding the murder.
The Fatal Night
On 14 January 2024, Prevez returned and waited until Sikkema was alone. He grabbed a kitchen knife and stabbed Sikkema 18 times as he slept, then left with cash. According to his confession, he immediately called Daniel Sikkema to report “mission accomplished” and later burned his clothes.
Confession and Arrest
Following his arrest on 16 January 2024, Prevez provided a written confession implicating Daniel Sikkema. He claimed Daniel had promised to pay him $200,000 and had given him instructions for the murder.
Investigation
Brazilian authorities launched a joint investigation with U.S. agencies due to the case’s international aspects. Interviews with Sikkema’s friends revealed that he had been going through a tumultuous divorce. He married Daniel Garcia Carrera, a Cuban immigrant more than twenty years his junior, in 2013 after meeting him at Art Basel in 2007. Carrera came from a poor background and had lived off Sikkema’s wealth during their relationship, according to court filings.
By 2020, cracks had appeared. Sikkema alleged that Daniel cheated and attempted to pressure him into an open relationship. During the COVID‑19 pandemic the couple spent long periods apart, with Daniel living in New York and Brent in Rio. Text messages produced in divorce proceedings show escalating arguments over money, infidelity and the care of their young son. In August 2022 Sikkema filed for divorce, asking the court to enforce a prenuptial agreement that limited Daniel’s access to his estate. Daniel counter‑sued, seeking full custody of their son and $6 million, while accusing Sikkema of hoarding assets and threatening mass murder at JFK airport.
Investigators believe Daniel’s motive lay in this financial dispute. Court filings show that in October 2023 Sikkema amended his will to disinherit Daniel and placed most of his assets in a trust for their son. Shortly afterward, Daniel allegedly began arranging payments to Prevez.
Legal Proceedings
January 19, 2024 — Formal Charges in Brazil
Brazilian prosecutors charged Alejandro Triana Prevez with aggravated murder. He was held in custody and remains in prison awaiting trial.
February 9, 2024 — Dual Murder Charges
Evidence gathered from phone records, bank transfers and Prevez’s confession led a Brazilian judge to charge both Prevez and Daniel Sikkema with homicide. Because Daniel remained in New York, Brazil requested his extradition.
March 2024 — Passport Fraud Arrest
U.S. authorities arrested Daniel on a passport fraud charge, alleging he used a forged Cuban passport for travel. He was placed under house arrest in New York pending extradition hearings.
January 2025 — Wrongful Death Lawsuit
The executor of Brent Sikkema’s estate filed a civil suit in New York seeking to prevent Daniel from inheriting any portion of the estate and to recover damages on behalf of their son.
February 11, 2025 — U.S. Murder‑for‑Hire Indictment
A federal grand jury indicted Daniel Sikkema on charges of murder for hire, conspiracy to commit murder and passport fraud. The indictment alleges Daniel paid Prevez through intermediaries, communicated through encrypted messages and planned to split the stolen cash. Prosecutors said Daniel faced a potential life sentence. Daniel pled not guilty and his attorney said he expected to be exonerated.
May 22, 2026 — Federal Conviction
After a trial in Manhattan federal court, a jury found Daniel Sikkema guilty on three counts: conspiracy to commit murder‑for‑hire resulting in death, murder‑for‑hire resulting in death, and conspiracy to murder a person in a foreign country. He now faces a mandatory life sentence. A sentencing date had not been set at the time of publication. His attorney maintained he would appeal.
Brazil Case — Ongoing
The case against Alejandro Triana Prevez in Rio de Janeiro remains pre‑trial as of mid‑2026. In January 2026, a Brazilian judge directed the defense to respond to forensic reports involving a laptop, a USB drive and a tablet before filing final arguments. No trial date has been set.
Legacy and Impact
Brent Sikkema’s murder sent shockwaves through the art world. Friends and colleagues remembered him as a champion of artists who spoke truth to power, such as Kara Walker and Sheila Hicks. He had built a gallery that gave marginalized voices a platform long before diversity became a marketable buzzword. Many saw his death as a tragic loss of a cultural visionary and a reminder of the fragility of life, even for those of means.
Within Sikkema Jenkins & Co., partners pledged to continue his mission of supporting emerging artists. The gallery organised a memorial exhibition in summer 2024, donating proceeds to LGBTQ+ youth charities and to an education fund for Sikkema’s son. Art critics wrote about Sikkema’s life and work, highlighting how he bridged the gap between commercial success and social conscience.
Outside the art world, the case spurred conversations about domestic violence, financial exploitation and the vulnerabilities of international marriages. Advocates argued that Sikkema’s death underscored how abusive partners may use wealth and jurisdictional loopholes to evade accountability. Calls for greater cooperation between U.S. and Brazilian authorities grew louder as details of the cross‑border murder plot emerged.
What Happened?
Why would a successful art dealer become the target of such a brutal murder? Investigative reports and trial testimony point to several interrelated factors:
Financial Motives
Daniel Sikkema relied on Brent’s money and faced losing access to the fortune once the divorce and updated will were finalized. Killing his husband before the divorce settlement may have preserved his inheritance and allowed him to collect on life insurance policies.
Control and Resentment
Friends say Daniel felt humiliated by Brent’s insistence on a prenuptial agreement. Court filings reveal he accused Brent of hoarding assets and controlling him. The idea of losing both financial support and social status may have fueled resentment.
Opportunity
Brent often traveled between New York and Rio, sometimes alone. Daniel knew his routines and had access to a key, making the Brazilian residence an ideal place to orchestrate an untraceable crime.
Coercion and Manipulation
Prevez’s confession suggests Daniel exploited Prevez’s financial hardship. His ability to influence an acquaintance into committing murder indicates a pattern of manipulation that prosecutors argued before the jury.
Public Perception and Media
The murder dominated headlines in both Brazil and the United States. Art publications mourned the loss of a pioneer, while mainstream outlets dissected the sensational elements of a wealthy dealer and his younger husband embroiled in a murder‑for‑hire plot. Social media users drew parallels to true‑crime documentaries and debated whether Daniel’s Cuban upbringing and immigration status influenced public perception.
Community members held vigils outside the Sikkema Jenkins gallery in Chelsea. They left flowers and notes near the entrance, and artists spoke about Brent’s generosity and mentorship. Coverage of the case also prompted discussions about mental health and domestic abuse within LGBTQ+ relationships, areas often overlooked in mainstream discourse. The May 2026 conviction renewed media attention, with outlets revisiting the full arc of the case from the Rio stabbing to the Manhattan verdict.

Conclusion
The Brent Sikkema case is a story of artistry, wealth, and tragedy. From his beginnings in Morrison, Illinois, Sikkema built a gallery that changed the cultural landscape and mentored countless artists. Yet behind the glossy veneer of the art world lurked a toxic marriage marked by financial dependency, jealousy, and violence. The murder and subsequent legal proceedings — culminating in Daniel Sikkema’s federal conviction in May 2026 — underscore the complexities of domestic relationships and highlight the importance of robust cross‑border cooperation in criminal investigations. As the parallel case against Prevez continues in Brazil, Sikkema’s friends and colleagues continue to honor his legacy through exhibitions, advocacy, and conversations about domestic abuse. Justice in the United States has been served; the full legal reckoning still awaits its final chapter in Rio.
