Her husband is arrested at the Miami airport for the disappearance of Ana María Henao, who disappeared in Florida, three months after her disappearance in Spain

The estranged husband of a missing Florida woman has been arrested at Miami International Airport for her disappearance in Spain.

Ana María Knezevich Henao, a 40-year-old Florida resident originally from Colombia, was reported missing on February 5 after she was unable to meet a friend to travel from Madrid to Barcelona for a conference.

David Knezevich was detained on Saturday as he returned from his home country, Serbia, where he had been for months.

The FBI and agents of the Spanish National Police carried out the arrest, according to EFE.

The Belgrade Interior Attaché Office and Colombian police were also reportedly involved in the arrest.

The couple had been going through a difficult separation when she disappeared, according to friends and family.

Henao had reportedly moved to Madrid in late 2023 in part to get away from her husband.

Investigators recovered surveillance footage of a man wearing a motorcycle helmet hanging around Henao’s Madrid apartment on Feb. 2, the day before her friends lost contact with her.

He was seen waiting for people to leave the building before entering around 9:30 p.m.

The same man is believed to have spray painted the lenses of two security cameras at the apartment building in Madrid’s exclusive Salamanca neighborhood.

Knezevich’s friend Sanna Rameau told DailyMail.com that she last exchanged messages with her on February 2.

The last message from Knezevich’s WhatsApp account, sent the next day, said he had “met someone wonderful.”

‘He has a summer house about 2 hours from Madrid. We are going there now and I will spend a few days there. The signal is irregular. I’ll call you when I get back,’ she said.

Another message detailed the circumstances of their first meeting, stating that they met on the street. ‘Incredible connection. Like she’s never done before,” she said.

Her family became concerned after they began receiving text messages in Spanish from Ana’s phone that did not appear to be written by the Colombia native.

‘That message in Spanish is as if it were translated from Google. It’s not her. She doesn’t say those things. As if no one in Spanish said it like that,’ said his brother.

Knezevich and her husband, also known as Dusan, had not yet formally filed for divorce at the time of her disappearance.

A March 12 report by Spanish publication El Cierre Digital cited “sources close to the case” who stated that the Scientific Police found biological remains in the missing woman’s home.

But his brother, Felipe Henao, recently appeared on NewsNation’s ‘Cuomo’ with a desperate plea to the public and denied the report about the remains, saying the family is still desperate for answers.

‘We want to know the truth. We want to know where my sister is,” Henao said. “If anyone has any information or advice, please contact the FBI or Spanish authorities.”

When asked about the alleged discovery of biological remains in his apartment, Henao said he asked the FBI if the report was true and “they told me it’s not.”

There were no further details on the details of the remains found.

Investigators “do not want to share any information because it could jeopardize the case.” I understand. Justice advances slowly,’ Henao added.

He said her case was being treated as a domestic violence matter as it progressed through the court system, and as a case of enforced rather than voluntary disappearance.

The couple ran a successful computer repair and support business from their home in Fort Lauderdale. Ana and Sanna had traveled a lot together during the holidays and communicated daily while Ana looked for a new apartment in the Spanish capital.
