David Kim, formerly of the Corcoran group, was sentenced to up to five years in prison this week for breaking into and stealing hundreds of thousands of dollars worth of property from a $7.6 million Upper West Side townhouse shortly after he'd sold it to the happy couple living there.

According to the New York Post, Kim sold the house at 141 West 81st Street in 2012, then waited eight months until art dealer Tina Kim and her husband Jae Chung—who hadn't changed the locks after moving in—left town for the Hamptons.

The Post reported on the dizzying litany of luxury goods Kim stole at the time:

"He decorated his apartment by framing the artwork on his walls," said one police source about David Kim, who was arrested last week on a slew of felony charges.

The source added, "The guy stole almost everything from their home, even humidifiers, cigar boxes and all of the woman's purses.

"One was worth $90,000. He has a drug and gambling problem."

...

Over the next 72 hours, he made repeated trips to and from the building, hauling away Louis Vuitton accessories, a Gucci wallet, a crystal pen, an Hermès passport holder, electronics and artwork, the sources said.

He allegedly stored the treasure trove in his apartment on the same block.

David Kim also used one of the victim's American Express cards on seven occasions to make $50,000 in purchases at various shops, court records claim.

"Even more than the loss of our property," Chung wrote in a statement read by the prosecutor at Kim's sentencing hearing, "We now live and sleep in a house where we worry that an intruder can enter and do us harm."

Lesson learned: when you move into a new place, change the locks! Especially if you're really, really rich.
