PLAISTOW - A Massachusetts man turned himself in to police Tuesday after authorities identified him as the suspected “Remorseful Robber” who allegedly snatched a woman's purse and then returned her money, GPS and a sorry note.

Christopher Piantedosi, 38, of Burlington, was charged with one count of theft by unauthorized taking or transfer following the incident on July 18 in which police say he grabbed a purse from a shopping cart at the Market Basket in Plaistow and swiped a wallet with $90 and a GPS.

After the theft was publicized, the thief showed up at the victim's home in Hampstead on July 26 and handed her $90, plus an extra $10, along with her GPS and a new charger, and a lengthy apology letter in which he confessed to the theft. He signed the letter, “Stupid.”

“I hope you can believe me when I tell you this will not happen again and I am sorry a million times over. I have some problems that I need to fix before I lose everything,” he wrote in the letter.

The thief ran away after handing the items over.

Deputy Police Chief Kathleen Jones said Piantedosi contacted the Plaistow Police Department on Aug. 4 and identified himself as the man wanted for the theft. His call came after news broke of how the thief now known as the “Remorseful Robber” had returned the items and left an apology.

Jones thanked the media for helping with the case.

Piantedosi was released on $2,500 personal recognizance bail and is scheduled to appear in the 10th Circuit - District Division - Plaistow Court on Sept. 13.
