American businesswoman Ana Knesovic moved to Madrid for a fresh start in December 2023, but disappeared weeks later after texting friends about meeting a mysterious man. When her estranged husband David emerged as the prime suspect, international investigators uncovered a sophisticated plot involving stolen license plates, disguises, and DNA evidence—only to have David take his own life in jail before trial. Ana's estranged husband David used a stolen Serbian license plate to enter Spain undetected, purchased a helmet and reflective vest, and spray-painted security cameras before Ana vanished from her Madrid apartment building.
