Year after prominent NYC art dealer killed in Brazil, his estranged husband is indicted in murder-for-hire plot

Federal prosecutors have indicted the estranged husband of a slain New York City art dealer in a murder-for-hire plot, saying he made multiple payments to the man arrested for the killing in Brazil during a contentious divorce.

Daniel Sikkema, 54, of New York was indicted Tuesday on murder conspiracy charges, as well as passport fraud.

"The defendant allegedly hired a hitman to facilitate the international murder of his husband and attempted to conceal his involvement in this callous plan," FBI Assistant Director in Charge James E. Dennehy said in a statement.
