He was the co-founder of Sikkema Jenkins & Co, a Manhattan art gallery that represents artists including Kara Walker, Louis Fratino, Arturo Herrera, the estate of Tony Feher, Vik Muniz, and Jeffrey Gibson.
[3] Sikkema began working with art in 1971 as the director of exhibitions at Visual Studies Workshop in Rochester, New York and opened his first gallery in 1976, in the city of Boston, Massachusetts, United States.
[8] According to the investigation, Daniel's motivation was the dispute over millions of dollars from Brent's estate, who was a partner in an important art gallery in New York.
[9] The police investigation said that Sikkema changed his will in May 2022, and his ex-husband, Daniel Garcia Carrera, the alleged mastermind behind the American's murder, was no longer the beneficiary of the inheritance.
[11] On July 1, the FBI, the United States Federal Police, has joined the investigation into the death of gallery owner Brent Sikkema in Rio de Janeiro and conducted the crime scene investigation in Jardim Botânico, alongside American prosecutors, Brazilian police officers from the Capital Homicide Division (DH) and members of the Federal Public Ministry (MPF).
