CHICAGO (CBS) — A West Town pub owner believes a group of thieves who have been preying on the neighborhood inadvertently saved the life of a German shepherd earlier this week.

A pickup truck parked near the Irish Nobleman Pub around 9:15 a.m. Monday, when the temperature was already around 80 degrees. Soon, the temperature inside the truck would be rising rapidly.

“They were walking down the street, looking in every car they walked past, and I believe they saw the laptop and smashed the window and took it out,” pub owner Declan Morgan said. “I don’t believe they knew the dog was in there.”

Morgan posted surveillance video of the incident on Facebook. He said he thinks the thieves accidentally saved the dog’s life by breaking the window.

The truck’s owner returned after about an hour to find his window broken and his laptop gone.

“I believe what comes around, goes around,” Morgan said. “He didn’t think it was a big deal that his dog was in there for an hour. I told him I would’ve smashed the window if I knew the dog was in there.”
