CHICAGO (CBS) – You’re expecting a package in the mail. The delivery person leaves it in your building’s lobby or on your doorstep, and the worst happens: It gets stolen.

It’s happening a lot this holiday season, especially in Logan Square. CBS 2’s Kristyn Hartman reports.

Jennifer Hyman lives in Logan Square, which has gotten some mention lately on the website Everyblock because of package theft.

Condo board president Robert Hyman is all too familiar. He got an email from a neighbor saying a couple of packages reported as “delivered” by UPS have gone missing.

Just one day after those gifts disappeared, they think they almost caught a package thief. Someone rang the buzzer. When Hyman went downstairs, he saw “a guy wearing jeans and a puffy coat,” Jennifer says.

Inside were two packages that could have been stolen.

The U.S. Postal Service is investigating some cases of missing packages and has potential suspects. Officials don’t say how widespread the problem is.

Everyblock posters from all different parts of the city also suggest thieves got ahold of USPS service keys to get into buildings.
