SEATTLE, July 28 -- Police searched for a second suspect Monday after gunfire erupted at a crowded food festival beneath Seattle's Space Needle, leaving three people dead and four others wounded, including a toddler. Another suspect, a 15 year old, was earlier arrested. Police said the two suspects were shooting at each other Sunday and one remained on the loose. Police did not have a description of the outstanding suspect, he said. Two people died at the scene and a third died at a hospital. They were described as two men, ages 19 and 44, and a 56-year-old woman. The four wounded, including a 2-year-old boy, were hospitalized and in stable condition early Monday, police said. The rest of the wounded were adults. The gunfire erupted a 6pm Sunday (local time) during the Bite of Seattle, an annual three-day festival that draws hundreds of food and retail vendors and performers. Dozens of officers were providing security at the event and some saw one of the suspects firing, Davis said. One suspect surrendered at the scene, but the other fled. A large number of police and emergency crews responded and began evacuating the area around the sprawling Seattle Center campus. Faith Adia Hunter said she and her friends had just gotten food from a crepe vendor when gunfire broke out. "We were about to start eating, then heard someone yell something, then we saw people start to run," Hunter said. "So we took off running, too." "We were right next to him when it started, so we took off running," Hunter added. Hunter said that in the scramble to find safety, she and others ran into the nearby Seattle Children's Museum. In the chaos, many vendors bolted toward the exits, abandoning their food stands. Hours later, some milled outside the police tape, wondering when they would be allowed to collect their tents, food and cooking gear. Roberto Ramirez, a vendor at the event, said he heard what sounded like firecrackers before people began yelling "shooter" and frantically running. "Suddenly everything was empty," he said. "People were freaked out."...
