Police evacuated a Los Angeles home improvement store Sunday after a caller said they had seen someone resembling a fugitive ex-police officer suspected of three killings.
Los Angeles police spokesman Gus Villanueva says the caller reported a sighting of 33-year-old Christopher Dorner. Police were sent to the Northridge area but Villanueva later said a search of the Lowe's Home Improvement store yielded no evidence that Dorner was there or had been there.
News helicopters earlier showed police helping customers and employees leave the store. A command post was established nearby.
The search since Thursday evening had focused on mountains 80 miles east of Los Angeles where Dorner's burned truck was found. But authorities have found no recent signs of Dorner.
LA officials announced a $1 million reward earlier Sunday for information leading to Dorner's arrest.
