The gunman also wounded three people before he was taken into custody (拘留). Police said this latest one in a series of mass (人数极多的) shootings in the United States, began about mid-afternoon at the Radisson Bay Harbour on Courtney Campbell. Witnesses (目击者) described a chaotic (处于混乱状态的)scene as the gunman fired shots in the lobby and pool area of the hotel before commandeering (强取) a car and fleeing. “I came here from New York City to escape the craziness there and wound up in one of the most insane (疯狂的) situations I have ever been in,” a witness to the shootings told local media (大众传媒). Police said the gunman fled to a nearby restaurant parking lot, where he shot and killed a woman and took another car. The gun-man, who had two weapons, was quickly cornered by pursuing (追捕,追赶) police and offered no resistance when he was taken into custody. It was the worst shooting rampages in Tampa since May of 1998, when a man who had been arrested as a suspect (嫌疑犯) in the shooting death of his four-year-old son escaped from police custody and shot to death three police officers. That assailant (攻击者) ,Hank Earl Cart, held police at bay for four hours at a gas station north of Tampa before killing himself. 　　The hotel killings were the latest in a series of mass shootings in the United States. last month, in the worst mass murder in Hawaii’s history, a 15-year employee of Xerox shot seven men to death at the Honolulu warehouse where he worked.
