1. Disaster at sea: Luxury cruise turns into nightmare.
On board the Costa Concordia, thousands of passengers were dining, drinking, attending a magic show, perhaps trying their luck in the casino. It was Friday night on the luxury cruise liner, sailing in the Mediterranean off the Italian coast with about 3,200 passengers and 1,000 crew members -- a night of entertainment and relaxation. There was annoyance, but no real alarm, when the lights went out -- not at first. Passenger Vivian Shafer said she thought it was part of the magic show. But those on board then heard an ominous scraping sound, and the 951-foot vessel gave a shudder. The ship began to list to one side.
2. All or nothing: Gingrich's 'Armageddon' strategy for South Carolina.
At his campaign events, Newt Gingrich -- the veteran politician who now sees himself as an unlikely political underdog -- blasts the theme song from the 1984 film "The Karate Kid." "Try to believe, though the going gets rough, that you gotta hang tough to make it..." goes the opening stanza from "You're the Best." "Fight 'til the end, cause your life will depend, on the strength that you have inside you." Days before the showdown in the South Carolina, Gingrich is locked in a close race with front-runner Mitt Romney in the most recent statewide poll. He has, in the first two contest states, been beaten down by Romney and his allies but is hoping the South Carolina primary on Saturday won't be the third and final act of his presidential run.
3. FBI asks for help finding body of missing Montana teacher.
The FBI is asking residents in North Dakota and Montana to help find the body of missing Montana teacher Sherry Arnold. The 43-year-old wife and mother was last seen on a morning run more than a week ago. "Based on investigative evidence gathered over the last few days, it is believed that Ms. Arnold may be deceased; her body has not been recovered," the FBI said in a statement Sunday. The agency asked property owners in North Dakota and northeastern Montana to check their land for disturbed soil, and to contact law enforcement if they see anything usual. Two men are in custody in connection to the investigation. Lester Waters and Michael Spell are being held in Williams County, North Dakota, on charges of aggravated kidnapping, Williams Country Sheriff's deputy Steve Thompson said.
