A Louisiana state trooper found a wallet on New Orleans' Bourbon Street during Mardi Gras and set it back to its owner at the trooper's expense.

Master Trooper John Jett's good deed would have gone unnoticed, but the wallet's owner, who goes by the username Wardo613 on the social news aggregation site Reddit, posted a photo Wednesday on the site of the wallet and Jett's note.

My name is John Jett, I am a trooper with the Louisiana State Police. While working Mardi Gras, I found your wallet on Bourbon St. at St. Louis St. I intended to leave it at a lost and found at the NOPD 8th District, however they really did not have one set up. I decided to mail it to you. I did go through your wallet in an effort to make sure the address on your (driver's license) was your correct address. Everything in your wallet is exactly as it was when I found it."

The grateful owner mentioned in his post that all of the money he had previously was still in the wallet when he got it back in the mail.

The post already has been viewed almost 1 million times.

Jett's actions "are truly a model of public service," said State Police Col. Kevin Reeves, head of the Louisiana law-enforcement agency.

"It makes us proud as an agency and as a law-enforcement agency that Trooper Jett would go above and beyond his duty as a public servant," Reeves said. "It represents the heart of the best of our agency.

Jett, 40, is based at Troop E in Alexandria, La. He's been a state trooper since April 1999, according to the Leesville (La.) Daily Leader, which named Jett its Public Safety Person of the Week in March 2011.

"Law-enforcement officers do these kind of acts of kindness every day, usually without fanfare. We'd have never known about this either if it hadn't been for the owner of the wallet," Reeves said. "Trooper Jett never mentioned it. He just considered it part of his job."

The wallet's owner said in comments to his original post that he plans on sending pizza to Jett and his colleagues as a thank-you.
