Laurence des Cars, the Louvre's president and director, is set to testify about the heist before the French Senate's Culture, Education and Sport Committee on Oct. 22.

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.

Museum security concerns rise after the latest Louvre robbery, as experts recall other major art thefts, including the Isabella Stewart Gardner Museum's still-unsolved heist from 1990.

Laurence des Cars, Director of the Louvre, has offered to resign following the daring theft of historic jewelry valued at 88 million euros ($102 million) from the Paris museum, referring to the heist as a “terrible failure” for the museum.

The theft of French crown jewels overshadowed the robbery of some $100,000 worth of historical coins from a museum dedicated to philosopher Denis Diderot.

NEW YORK (AP) — Just days after a stunning heist at the Louvre Museum in Paris, speculation is growing around where the lavish, stolen jewels that once adorned France’s royals might end up.

The Louvre reopened to visitors on Wednesday, three days after thieves pulled off a spectacular jewel heist worth €88 million.

At the Louvre, a lack of security cameras may impede the investigation. According to the BBC, at least a third of the rooms in the wing where the crime took place don’t have video surveillance.

So says retired FBI agent Geoffrey Kelly, who for two decades led the investigation into the 1990 theft of masterworks from the Isabella Stewart Gardner Museum. Kelly, now a partner in a company that assesses museum security, believes jewels were pilfered from the Louvre because they are easier to sell than a painting.

Thieves broke into the museum's Galerie d'Apollon and made off with "priceless" jewelry, French interior minister Laurent Nuñez said.
