RESCUE: HIGH-TECH HELP

Rescue workers searching for survivors in the deadly mudslide at La Conchita, Calif., got help from a prototype ground-radar device that can detect a living person trapped under 20 feet of debris and rubble. Called Rescue Radar, the suitcase-size black box is able to sense tiny movements like the intake of a breath. By the time the machine went into action at La Conchita, where 10 died, there were no more survivors, but rescue officials say the one-of-a-kind unit made by Bechtel Nevada holds great promise. "We want to have every possible shot for finding people," Los Angeles County Fire Capt. Larry Collins says. "I think we're going to start seeing lives saved with this."
