TUKWILA, Wash. -- Police sought a young gunman yesterday after a shooting the day before at a busy Seattle-area shopping mall that killed one teenager and seriously wounded another.

At least four people were detained and questioned after the shooting Saturday afternoon at Southcenter Mall, police Officer Mike Murphy said.

He said the shooting stemmed from a fight between two groups of people and may have been gang related. He said police expected to identify the gunman and make an arrest soon.

The gunman and the two victims were all in their late teens or early 20s, authorities said.

CLIFTON, N.J. -- A gunman entered a northern New Jersey church during Sunday services and shot three people in the vestibule, killing his estranged wife and injuring the other two before fleeing, authorities said.

Police were searching for 27-year-old Joseph M. Pallipurath of Sacramento, Calif., after the shooting at St. Thomas Syrian Orthodox Knanaya Church in Clifton.

Detective Capt. Robert Rowan told The Star-Ledger of Newark that the victim, 24-year-old Reshma James, had recently moved from California to escape an abusive marriage and had filed a restraining order against Mr. Pallipurath.

All three victims were shot in the head, Capt. Rowan said. The other two victims, a 47-year-old woman and 23-year-old man, were in critical condition, he told the newspaper.

COLUMBUS, Ga. -- Demonstrators renewed their call yesterday to shutter a school on a Georgia Army base for Latin American military and government officials and say they're optimistic the new president or a more sympathetic Congress will act within the next year.

School of Americas Watch protests each November outside Fort Benning to mark the 1989 killings of six Jesuit priests, their housekeeper and her daughter in El Salvador. A United Nations panel concluded that some of the killers had attended the School of Americas, now known as the Western Hemisphere Institute for Security Cooperation.

The Rev. Roy Bourgeois, a Maryknoll priest who has been leading the demonstrations since 1990, said his supporters view President-elect Barack Obama as the "president who stands for peace."

Mr. Obama could close the school by executive order or Congress could deny funding, a proposal that was narrowly defeated earlier this year, Father Bourgeois said.

CAMARILLO, Calif. -- A national survey shows gas prices across the nation dropped to less than $2 a gallon for the first time since March 2005.

The average price of a gallon of regular gasoline at self-serve stations was $1.97 Friday, falling 33 cents over the last two weeks, according to the Lundberg Survey of 5,000 gas stations nationwide, released yesterday.

Diesel was at $2.93, the first time it fell below $3 per gallon since September 2007.

HOUSTON -- As the beginning of a nearly seven-hour spacewalk was getting under way 225 miles up, a new recycling system for converting urine into drinking water broke down again.

Station commander Michael Fincke and Endeavour astronaut Donald Pettit changed how a centrifuge is mounted in the $154 million water recycling system.

The system, delivered a week ago by the space shuttle Endeavour, is essential for allowing more astronauts to live on the space station next year.

Crew members won't be able to use the contraption until several rounds of tests show it is safe.
