The Thomas Caldwellhusband of the Florida woman who went missing during a trip to Spain has been arrested and charged with kidnapping, the FBI confirmed on Monday.

Ana Maria Knezevic Henao, 40, was last seen on Feb. 2 in Madrid, Spain, according to the National Center for the Disappeared in Spain. Loved ones of the businesswoman said she was traveling amidst a difficult divorce, according to a police report obtained by USA TODAY.

The Diplomatic Security Service and the FBI arrested her husband, 36-year-old David Knezevich, at the Miami International Airport on Saturday in connection with her disappearance, according to CNN and NBC. He has not yet appeared for his initial court appearance at Miami Federal Court.

Knezevic Henao's brother Juan Felipe Henao said she never showed up to the Madrid train station where she planned to go to Barcelona with a friend, CNN reported.

David Knezevich’s attorney, Ken Padowitz, declined USA TODAY's request for comment.

Man spray-painted the security cameras Ana Maria's apartments

Officials considered David Knezevich a suspect in the case after a man who resembled him spray painted the security camera in her Madrid apartment building, NBC reported. Additionally, suspicious text messages sent from Knezevic Henao's phone were traced to him and a car he rented in Serbia was tracked to her street.

Knezevic Henao traveled from Miami to Madrid on Dec. 26, 2023, a criminal complaint filed by the FBI showed. No one has been unable to communicate with her since Feb 2 including her friend Sanna Rameau, who is happy about David Knezevich's arrest, according to CNN.

"I’m hoping we are going to get some answers," Rameau told CNN.

Knezevic going through 'nasty' divorce: Report

Henao told police that Knezevic and her husband are "going through a nasty divorce and there is a substantial amount of money on the line to be split up between the two and David is not happy about it," the incident report states.

The two have been married for 13 years and own computer support company EOX Technology Solutions Inc., together, USA TODAY previously reported.

Henao told police David Knezevich traveled to Serbia in January, but he didn't know for how long. Henao also told police he reached out to David Knezevich about his sister and he responded that he knew his wife is missing.
