LOS ALTOS (CBS SF) — A pair of brazen thieves used a stolen truck to slam through the store front of a Los Altos jewelry store, smashing display cases and escaping with an undisclosed amount of merchandise — a crime captured on the store’s security camera, authorities said.

Los Altos Police said the smash-and-grab robbery took place at Marcel Jewelry Design at 262 Main Street around 2:30 a.m. on Monday.

On the video, the two masked thieves use the stolen truck as a battering ram, slamming the vehicle into the building several times before the store front comes tumbling down.

The suspects — one wearing black hoodie and the second with a bright yellow caution jacket on — leap through the debris and use a hammer to break into the display cases. They leave wall display cases untouched and then flee the building.

The smash-and-grab robbery was over in minutes. Police said the suspects left the truck behind and fled in another vehicle.

This is third break in at the store in just four months, according to Marcel, the store’s owner. Marcel says cleaning up the mess and getting back to business may not be worth the hassle this time around.

“The headaches of getting contractors. The headaches of getting glass repair. The headaches of cleaning it up. Lotta headaches,” he said.

On top of multiple burglaries, Marcel is living with stage four colon cancer and has been for four years. “I’m 76 years old with cancer. Who the hell wants to go to work? Let me enjoy the rest of my money and my life.”
