A security guard on duty tried to stop them, but it was too late. He said he heard the crash and called 911.

Shoppers are on high alert.

"It's getting hot, so you will see a lot more stuff like this. People are crazy. I thought that only happened in movies,” Daniel Coakley said.

"People work hard for their money, then someone goes and takes the machine. (It's) terrible," Carolyn Brown said

Police said they found cash, broken light pieces from the truck, a license plat holder and a tire near the crash site.

They said they hope the items and surveillance video will lead them to the thieves.

The security guard said he saw two people in the truck, but could not give a good description.
