Police looked all over the world-Russia, Japan, and Brazil. They even interviewed Perugia, but they let him go! Police continued to look for the painting. Two years passed before Perugia brought Mona Lisa to a man in Florence, Italy, who dealt in art. Florence is the city where Leonardo da Vinci painted Mona Lisa. Unfortunately for Perugia, the art dealer called the police, who arrested him. Perugia said he wanted to return Mona Lisa to its"real"home. The police believed he wanted to sell copies of the painting and keep the original for himself. To this day, nobody really knows why he did it.
