Hewitt police are investigating a burglary at Happy Endings Dog Rescue.

Police Chief Jim Devlin said authorities are working to develop suspects and enhance surveillance footage of the break-in at the shelter, 516 Hewitt Drive, which occurred early Tuesday morning.

Police were notified about 6 a.m., but security footage indicates the break-in, committed by two individuals, occurred around 1:20 a.m.

It appears that two people broke a window near the facility’s front entrance to force their way into the building, Devlin said. The two took a cash register and a safe, then fled, according to the chief.

“They were in, out and gone in 40 seconds,” Devlin said.

About $600 was taken, he added.

No physical descriptions of the burglars were available Wednesday, Devlin said.

Officials from the rescue organization could not be reached for comment Wednesday afternoon.
