Thieves smashed open steel doors on the north side of the Costco, 1600 Expo Parkway, about 2 a.m. The two men drove their car through the double doors in reverse, smashing them open.
Once inside, the thieves broke a large glass jewelry display case, said Sacramento Police Sgt. Louis Pease.
"They took every piece of jewelry out of there," Pease said.
Descriptions of the men were not available, in part because the store was dark when the break-in occurred. Police are checking video of area businesses for possible images of the burglars or their car.
PHOTO CUTLINE: Police say two burglars rammed their vehicle through these doors at the Cal Expo Costco store early this morning then stole all the jewelry inside.
