Register Robbers: Pair of armed grocery store crooks make clerk go from till to till

WANTED IN SEATTLE -- Robbing a cash register is one thing, but the pair of armed grocery store robbers Seattle police are looking for -- went from till to till – cleaning out an entire row of registers. Watch the video and check it out from the start. They enter the QFC on Capitol Hill. One in black, the other wearing a red hoodie, and both with their pant legs rolled, meaning they could be riding bicycles, but we don't really know. The two head straight for the liquor aisle, then loiter a bit, then they start going to all the tills, trying to get them open. But, when that didn't work, they decided it was time to get some help -- flashing a gun to the clerk, and telling him to open a safe. The clerk tells them there’s only paper in there, so they have him go from register to register, putting the cash in a bag, before the two take off. Surveillance video caught them as they ran away through the parking lot of a nearby business Detectives believe one of them is in his teens because of his high voice.
