Jitterz Java on Northwest Boulevard in north Spokane was robbed by a man with a gun today, hours after a Jimmy John’s delivery driver was also robbed by a man wielding a gun. There are no indications that the two cases are related, said Spokane police Lt. Dean Sprague. “We’re treating them as separate incidents,” he said. The Jimmy John’s driver went to the 1800 block of East South Riverton shortly after 5 p.m. to deliver an order when he was confronted by a group of people. One of them, a white man wearing a grey hoodie with black on it and a ski mask, was holding a gun, Sprague said. The coffee stand was robbed by a man who walked up to the window and displayed a gun at 6:40 p.m. He ran west with an undisclosed amount of cash. He is described as a white man wearing a black hoodie and a full-face ski mask. A police dog was unsuccessful in tracking the thief. Sprague said police are not sure if the Jitterz Java robbery is related to other recent coffee stand robberies. “That’s certainly being looked at,” he said.
