The Mona Lisa mystery might be one step closer to being solved. Bones found by archaeologists in a Florence church might belong to the infamous Mona Lisa, according to the AFP.

The bone fragments were tested, but results are inconclusive, according to the Atlantic Journal Constitution. They were tested against the DNA of Lisa Gherardini, the wife of Francesco del Giocondo, who many believe to have been Mona Lisa's real life identity.

No one knows for sure who the identity of the model was, some believing Da Vinci used multiple female models, others saying he used a male model, and a few believing the Mona Lisa is a kind of self-portrait.

Carbon-14 tests were done on three skeletons found in the church, according to the International Business Times. After the tests, the team narrowed down the search to one of the skeletons, determining it was the right age and build. Unfortunately, not enough evidence could be found to solidify their beliefs.

The search began in 2011, and while no concrete evidence has been found linking this skeleton to that of Gherardini, or her to the painting itself, researchers are not giving up any time soon.
