The first break-in happened November 1. Jewelry was taken from a house on North Monroe. Then on November 4, someone broke into a house on First Street and stole electronic items.
Police say in both cases, the thieves forced their way into the homes. Both took place while no one was home.
"People are just amazed because everybody's out in the yards. Children are everywhere. And it was really bold how they did it right in the morning. Just broke into a front door," said Hinsdale resident Brian Moran.
Police are urging residents to report any suspicious activity, and asking those with home security systems to be sure they're activated at night or when leaving home.
