Employees at Heartland Computers say someone used a rock to shatter the glass door of their store on South Minnesota Avenue.
From there, the owner thinks the burglars kicked in the display case to grab five computers, worth about $2200.
Store managers say they don't have a lot of clues to go on.
"We discovered that the cameras got unplugged somehow," Office Manager Lisa Foley said. "So we have no picture of them. So we got to base it all off the serial numbers and hope they try to pawn it."
Employees at a business next door noticed the break-in and called police Wednesday morning.
Managers say they plan to add more security in the future to prevent something like this from happening again.
