Two traces of DNA were found in one of the helmets and one of the gloves suspects left behind after a jewelry heist at the Louvre on Sunday, French police told ABC News.

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.

In total, thieves stole about €88 million worth of jewels on Sunday, including a necklace Napoleon Bonaparte gave to Marie-Louise of Austria, the tiara, necklace and earrings of Queen Hortense, and a diadem, diamond bow brooch and reliquary brooch that once belonged to Empress Eugénie, wife of Napoleon III.

Master jeweler Stephen Portier said the Louvre robbers might recut the stolen gems, which would significantly decrease their value.

Thieves made off with about 2,000 gold and silver coins from a French museum — just hours after the audacious $1 million raid at the Louvre.

Burglars who broke into the Louvre museum in Paris on Sunday initially failed to open the display cases with angle grinders, the Le Parisien newspaper reported on Thursday, citing museum surveillance footage.

No security cameras were monitoring the second-floor balcony where thieves gained access to the Louvre to steal historic jewels worth over $100 million, the museum’s director told a French Senate committee hearing.

Some 100 investigators are still trying to identify those responsible for stealing eight of France's crown jewels.
