IRVINE, Calif. (AP) - 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.

VANDENBERG AIR FORCE BASE, Calif. (AP) - A rocket carrying an Earth observation satellite is scheduled to blast off from the California coast on a mission to keep a continuous eye on the planet's resources.

The countdown for the Atlas V launch begins Monday morning from the Vandenberg Air Force Base along California's central coast.

The Landsat satellite is the eighth of its kind to be launched since 1972 to track glaciers, forest fires, crop production and coastlines. Unlike its predecessors, the latest carries more powerful sensors and can return more images.

For the past four decades, the polar-orbiting Landsat satellites have documented changes to Earth's surface including the effects of deforestation and urban sprawl.

The $855 million mission is managed by NASA and the U.S. Geological Survey.

ARLINGTON, Texas (AP) - Thousands are expected to attend a public memorial service Monday for former Navy SEAL sniper Chris Kyle, who was killed at a Texas shooting range allegedly by a young veteran he was trying to help.

Mourners will gather at Cowboys Stadium to pay tribute to the 38 year old who was reputed to be the deadliest sniper in American military history.

Kyle left the Navy in 2009 after four tours of duty in Iraq and wrote the best-selling book "American Sniper."

Twenty-five year old Iraq War veteran Eddie Ray Routh has been charged with killing Kyle and his friend Chad Littlefield at a gun range Feb. 2.

Kyle will be buried at the Texas State Cemetery in Austin after a 200 mile funeral procession starting in the Dallas area Tuesday morning.
