The investigation into the disappearance of Ana María Knezevich Henao took a decisive turn when her husband, David Knezevich, was apprehended by the FBI and Spanish National Police at Miami International Airport after flying in from Serbia. Accused of involvement in his wife's disappearance in February, he had been under suspicion since Ana María vanished on February 2.

Evidence linking Knezevich to Ana María's disappearance included security footage showing a man, believed to be him, spray-painting the security camera outside her Madrid apartment on the night she went missing. He then exited the building carrying a suitcase, a move that was premeditated, as footage showed Knezevich purchasing spray paint and duct tape hours before the incident.

Spanish police discovered further clues when they interviewed a woman who claimed that Knezevich asked her to translate a suspicious text message allegedly sent from Ana María's phone to her friends. The text, written in English and Spanish, stated that she had decided to leave with a new man she just met. Friends immediately doubted the message's authenticity, given her recent divorce from Knezevich.

The trail deepened when a driver reported that his license plates had been stolen. That night, a plate reader on Ana María's street recorded the stolen plate number. A Peugeot with the stolen plates was later spotted at a toll booth outside Madrid. When Knezevich returned the rented Peugeot five weeks later, the plates had been changed, the windows tinted, and the odometer showed it had traveled almost 4,800 miles.

Authorities suspect Knezevich meticulously planned his wife’s disappearance. The investigation, led by the Court of Violence against Women in Madrid, remains highly sensitive and secretive. Both Spanish and American officials are working together to ensure a comprehensive investigation and uncover the truth behind Ana María's fate.

Her disappearance has profoundly impacted her friends and family in Fort Lauderdale, where she lived. Loved ones have held vigils, expressing hope for justice. While the arrest of David Knezevich is a significant development, many questions remain as both Spanish and U.S. authorities work tirelessly to resolve the case and provide closure for Ana María's loved ones.
