The Louvre Museum heist was a classic case of German efficiency. That at least is how a German freight lift manufacturer jokingly portrayed it in an ad.

Investigators have collected more than 150 trace samples, including fingerprints, bits of DNA and other silent evidence, from the scene of the Louvre heist.

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.

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

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.

As French police, government officials and top executives at the Louvre Museum continue to scratch their heads over how thieves managed to brazenly steal priceless jewelry in broad daylight, a German company is seizing the moment and grabbing its 15 minutes of fame.

A German company inadvertently embroiled in the Louvre Museum heist after one of its lifts was used in the theft is making the most of its free publicity - by launching a new advertising campaign.
