David Knezevich was the prime suspect in the disappearance of the US citizen last February while the couple were involved in a multimillion-dollar divorce

David Knezevich, the ex-partner of Ana María Knezevich Henao, who disappeared in Madrid, Spain, at the beginning of February, has been arrested at Miami International Airport in connection with the case.

Knezevich had been from the outset the prime suspect in the investigation, as the couple were going through a difficult separation involving a dispute over the multimillionaire patrimony they managed. Knezevich is of Serbian origin and Ana María is a U.S. citizen born in Colombia. They both lived in Miami, where their businesses were based, until she decided to move to Madrid at the end of 2023 to get away from her husband.

The Spanish National Police reported the arrest, which took place Saturday in an operation involving the Spanish Interior Ministry’s attaché office in Belgrade, the FBI, and the Colombian police.
