A robbery worthy of a movie script is challenging investigators in Messina, Sicily. Thieves managed to enter a museum, dismantle one of the most important masterpieces of the Italian Renaissance and leave within minutes.
But then they did something that no one can explain: they left two pieces of the work outside the museum, carefully leaning against a wall.
The incident occurred at around 8:47 p.m. on August 15, as the center of Messina was packed with tens of thousands of people for the traditional religious holiday of Ferragosto. At least two men cut through the fence of the Regional Museum of Messina, forced open a side door and entered.
Their target was extraordinary: the “Polittico di San Gregorio,” Antonello da Messina’s 15th-century masterpiece and one of the Renaissance master’s most important works. The work consists of five surviving panels.

The thieves also took a small double-page painting, depicting the Madonna and Child on one side and Christ in the Pietà on the other, attributed to Antonello da Messina.
The timing of the robbery seems to have been no coincidence. Every August 15, Messina holds its famous Vara procession, a tradition that dates back to 1535. A 14-meter-high pyramidal structure representing the Assumption of the Virgin Mary crosses the city, while over 150,000 people gather in the center. Hundreds of police are deployed for security and the main streets are blocked.
Meanwhile, the outskirts of the city, where the museum is located, remain almost empty.
“If there is one day out of the 365 days of the year that a thief would choose to carry out a robbery in Messina, it would be August 15,” an investigator close to the case told The Guardian.
According to investigative sources, two masked men wearing motorcycle helmets may have entered the museum, while two other accomplices allegedly stayed outside to observe the area.
But here the mysteries begin.
Investigators are still trying to determine exactly how the robbers entered the museum grounds. One clue is that they may have gone through an adjacent apartment complex. After cutting through the fence, they allegedly went straight to a side door.
And that very door was one of the few entrances that, according to investigation sources, was not equipped with an alarm.
Security camera footage has raised an even bigger question. The entire robbery appears to have lasted only two to three minutes.
"How did the thieves manage to remove all five panels so quickly and how did they know that that door had no alarm?" asks art historian Valentina Certo, affiliated with the University of Messina.
For this reason, investigators are also looking into the possibility that the perpetrators may have had information from inside the museum. ANSA reported that an employee was under investigation for allegations of inconsistencies regarding the alarm system, although police sources have disputed this report.

International art recovery expert Christopher Marinello warns that checking an internal track is normal practice in such robberies and does not automatically mean that an employee collaborated with the thieves.
Even the masterpiece's own alarm system raises questions. While the door used by the robbers may not have had an alarm, the Polittico di San Gregorio was protected by a system that was supposed to be activated as soon as the work was moved.
And the alarm, according to investigative sources, was activated.
According to police sources quoted by TG La7, a guard told investigators that he had heard the alarm, but had turned it off, thinking it was a false signal.
Just about ten minutes after the robbery, a woman walking by the museum noticed something unusual on a low wall.
"There are museum paintings on the street, as if someone stole them and left them here. They are big and worth a lot of money," she told police in a recording obtained by The Guardian.
There were two of the five panels of Antonello da Messina's masterpiece.
But they hadn't been thrown away during the escape. They had been carefully placed, leaning against the wall.
And that's precisely one of the questions that continues to torment investigators: why would someone enter a museum, dismantle a five-panel masterpiece in just a few minutes, and then leave two of them outside?
Authorities continue their search for the missing authors and works, while the August 15 robbery has become one of the most enigmatic art thefts in Europe in recent years.
In Messina, investigators already have the cameras, the alarm, the possible escape route and two of the abandoned panels. What they still don't have are the answers to two of the most important questions: how did the thieves know so much about the museum and why did they take a masterpiece and leave it partially behind?
