Federal prosecutors opened a murder-for-hire trial Tuesday in Manhattan, alleging that Daniel Sikkema arranged the stabbing death of his estranged husband, prominent contemporary art dealer Brent Sikkema. The 75-year-old victim was discovered in his Rio de Janeiro townhouse in December 2023 with 18 stab wounds, prompting an international investigation that culminated in the defendant’s arrest in New York the following year. The proceedings will weigh witness recollections of a deteriorating marriage against financial and digital records tracking communications between the defendant and a suspected gunman.
Assistant U.S. Attorney Nicholas Pavlis outlined the government’s case to the federal jury, stating that prosecutors will present witness testimony, location data, and financial documents linking Daniel Sikkema to the alleged assailant before and after the killing. The government contends that Sikkema, 55, communicated frequently with the suspect and funneled more than $10,000 to him, with additional funds promised as the plot advanced. Pavlis told jurors that recorded interviews will show the defendant making false statements to FBI investigators shortly after the body was discovered.
The prosecution’s first witness, retired pharmacist Angela Liriano, testified about a December 2023 phone conversation with Daniel Sikkema. Liriano said she was shocked by the tone Daniel used when she mentioned hearing that Brent had traveled to Brazil. “He said: ‘Oh, well I truly hope that he’s dead, that he dies,’” Liriano told the court. The testimony marked the government’s effort to establish a clear premeditated intent ahead of the physical evidence phase.
Pavlis told jurors that Daniel Sikkema bragged to others about expecting a larger financial payout from his husband’s death than he would have received through divorce proceedings. The couple had separated in 2022 after building a multimillion-dollar estate together. During the same December conversation, Liriano noted that Daniel complained about a proposed $6 million divorce settlement, stating he wanted $8 million instead. “After his husband was brutally killed, the defendant tried to cover his tracks and cash in,” Pavlis said.
Defense attorney Florian Miedel opened by cautioning the jury against drawing conclusions from circumstantial evidence alone. He emphasized that the prosecution’s case relies heavily on assumptions, suggestions, and inferences rather than direct proof. “Life is messy. The truth is not always obvious,” Miedel said, urging jurors to recognize that individuals frequently make extreme, emotionally charged statements during contentious marital breakdowns. He reminded the panel that no hired gunman will take the stand and that physical evidence directly tying his client to the crime scene remains absent.
Miedel also contested the financial motive presented by prosecutors, telling jurors there is no documentation proving his client knew prior to the killing that his financial position would improve with Brent’s death rather than through litigation. He highlighted the couple’s shared domestic responsibilities, noting that Daniel Sikkema was actively raising a 13-year-old son with his husband and would never intentionally separate a child from a parent he loved. Miedel instructed jurors not to hold it against the defendant if he exercises his constitutional right not to testify, reaffirming that the burden of proof rests entirely with the prosecution.
Brent Sikkema co-owned a Manhattan contemporary art gallery that now operates under the name Sikkema Malloy Jenkins. The gallery’s public records state it has represented internationally recognized artists, including Kara Walker, Vik Muniz, and Arturo Herrera, for nearly three decades. Daniel Sikkema, who holds dual U.S. and Cuban citizenship, was arrested in New York in April 2024 and remains held without bail on federal murder-for-hire charges.
An alleged hitman tied to the case was apprehended in Brazil following a joint investigative effort and remains jailed there pending separate proceedings. The Brazilian arrest provided the initial geographic and transactional links that allowed U.S. authorities to build the federal indictment. Defense counsel reiterated that the Brazilian suspect will not appear as a witness for either side, leaving the Manhattan jury to piece together the narrative from phone records, bank transfers, and courtroom testimony.
Liriano, who worked closely with the couple through her pharmacy business and accompanied them on a 2018 trip to Cuba, offered a contrasting portrait of the defendant’s earlier conduct. She described Daniel Sikkema as historically courteous, recalling that he showed her around Havana and was “very nice, always.” Her testimony bridges the personal history of the couple with the legal arguments now unfolding, setting a baseline for subsequent witnesses who will address the financial disputes, travel logs, and digital communications that define the remainder of the trial.
