At a news conference Friday evening, Los Angeles Police Chief Charlie Beck identified the suspects as Bryan Barnes, 20, of Los Angeles and Javier Bolden, 19. The mayor, the father of a college-age daughter, said his heart went out to the Chinese students' parents. The arrests came days after the parents of the slain students filed a wrongful death lawsuit against USC, saying the school misled them when it claimed that it ranks among the safest in the nation. On Friday afternoon, one woman who witnessed Barnes' arrest from her front lawn said that at first, she thought she was watching the taping of a television police drama. "It was quiet, calm," said the woman, who declined to give her name. We thought at first they were a crew filming 'Southland.' She said dozens of detectives, plainclothes officers and SWAT team members descended on the 1200 block of 91st Street. Children played kickball in the street, and an ice cream truck cruised by. Arresting officers swooped into a bright blue, two-story house in the middle of the block; the house is divided into five apartments. They emerged soon after with a man in handcuffs, she said. The woman, who said she has lived on the block for years, said she did not recognize the man, who had a medium build and appeared to be in his early 20s.
