Search continues for missing Utah woman

SALT LAKE CITY — Police had little to go on Sunday in the search for a Utah woman who hasn't been seen for a week.

Twenty-eight-year-old Susan Powell was reported missing from a Salt Lake City suburb in a case that police call suspicious.

She left behind two children and a husband, who says he doesn't know what happened to her.

West Valley City police Capt. Tom McLachlan says at least eight detectives worked the case Sunday, fielding any tips or leads they can get from the family or friends.

GOVERNMENT CAMP, Ore. —Fears of an avalanche on Mount Hood forced rescuers to use a helicopter and airplanes in their search for two missing climbers on Sunday, a day after crews found the body of their climbing companion on a glacier on Oregon's highest mountain.
