Gun used by agent credited with toppling Capone headed from New Jersey to Las Vegas museum

A gun with a colorful history is going to be transported from New Jersey to a mob-themed museum in Las Vegas.

The gun belonged to late IRS criminal investigator Michael Malone, who was instrumental in bringing down legendary mobster Al Capone.

The Smith & Wesson .38 special is believed to have been used by Malone when he went undercover to infiltrate Capone's organization, and it may have come from Capone's men.

Malone died in 1960, and his relatives in New Jersey have held onto the gun over the years. Recently, Malone's great-nephew negotiated to sell the gun to The Mob Museum in Las Vegas.

It's scheduled to be unveiled in an exhibit next month that focuses on the contributions of U.S. Treasury Department agents in combating organized crime.
