     A gunman killed eight people at a mall in Omaha this afternoon and then killed himself, setting off

panic among holiday shoppers, the police said.

     "The person who we believe to be the shooter has died from selfinflicted gunshot wounds," Sgt.

Teresa Negron of the Omaha Police Department said at televised news. "We have been able to clear

the mall," she said. "We don't believe we have any other shooters." The police said that at least five

other people had been injured in the shootings.

     She did not give the shooter's identity. "We are still conducting the investigation," Sergeant Negron

said, adding that the city's mayor, who was out of town, was on his way back to Omaha. She said the

police received a 911 call from someone inside the Westroads Mall on the west side of Omaha, and

shots could be heard in the background. The first police officers arrived at the mall six minutes after

the first call, she said, but by then the shootings were over.

     It is reported that the gunman left a suicide note that was found at his home by relatives. A law

enforcement official who spoke on condition of anonymity (匿名) said the note indicated that the

gunman wanted to "go out in style".

     The shootings broke the usually banal routine of holiday shopping. The gunman was said by some

witnesses to have fired about 20 shots into a crowd. Some customers and workers ran screaming from

the mall, while others dived into dressing rooms to hide from the shooter.

     Shoppers and store workers were trapped inside the mall, which has roughly 135 stores. Others

streamed out of mall exits with their hands raised. The president was in Omaha this morning to deliver

a speech, but he had left the city by the time the shootings took place.
