Smash-and-grab robbers rip off jewelry from Stanford Bloomindale's

Inside the store you could see the display cases that had been smashed were covered with drop cloths. KTVU counted six of them, some in the wristwatch area, the others holding jewelry.

"Palo Alto there is a lot of wealth here, so people are going to come to the areas where there's money," said Alan Winkleman of San Jose.

A similar crime happened in February. You can still see a tire mark on the carpet at the Keeble and Shuchat camera store on California Avenue after someone drove a minivan through the front doors and stole some camera equipment.

"We're surprised they are still at it. I hope the police will catch them in the end," said store employee Don Dimitratos.

Police say they don't know if the two cases are related.
