Christopher A. Marinello, CEO and founder of Art Recovery International, joins “Forbes True Crime” to discuss the shocking Louvre heist.

The Louvre, in Paris, home to Leonardo da Vinci’s “Mona Lisa,” was robbed by four thieves on Sunday morning in its Apollo Gallery, where some of France’s most prized jewels and other royal artifacts are displayed.

The Louvre Museum opened its doors at 9 a.m. on Wednesday morning in Paris -- the first time it has welcomed the public since Sunday’s robbery.
