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.

NBC Boston spoke to an art theft expert who is also the director of security and chief investigator at the Gardner Museum about the logistics of this heist at the Louvre and what the thieves might be planning to do with the crown jewels. The plot was carried out just 30 minutes after the Louvre opened on Sunday morning.

The Louvre Museum robbery of priceless jewelry may prompt museums worldwide to review their security programs and protocols, according to experts.

Sunday’s robbery at the Paris museum could be the latest example of thieves targeting museums for jewels and precious metals to break down and sell on.

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.

The Louvre museum was hit by a brazen daytime jewel heist, forcing the Paris institution to close its doors for a second day in a row.

The Louvre remained closed Monday, a day after historic jewels were stolen from the world’s most-visited museum in a daring daylight heist that prompted authorities to reassess security measures at cultural sites across France.
