Anaheim, Calif., Police Make Arrest in Killing of Homeless Man ANAHEIM, Calif. - The man believed to have killed four homeless men in Orange County over the last month is now in custody, according to law enforcement officials. The suspect, Itzcoatl Ocampo, was arrested Friday night after a homeless man was fatally stabbed behind a Carl's Jr. restaurant in Anaheim - the most recent in the series of killings. Police authorities insisted on Saturday that Mr. Ocampo, a 23-year-old resident of Yorba Linda, Calif., was responsible for all four murders. "We are extremely confident that we have the man who is responsible for the murder of all four homeless men in Orange County," Chief John Welter of the Anaheim police said. Police officials would not offer details about how Mr. Ocampo had been linked to all four of the murders. But the Friday night slaying, which led to his arrest, fit the pattern they had already established: a lone, middle-aged homeless male stabbed to death in the same area of inland Orange County where the previous attacks had occurred. The three prior killings had sent a shiver through Orange County's homeless community. People who usually kept to themselves began flooding into homeless shelters and sleeping in groups. The police, meanwhile, convened a task force that brought together several local law enforcement agencies, as well as the Federal Bureau of Investigation. But they had been left with few leads, aside from a few grainy security videos, including one that showed a man walking toward the first victim. Dozens of people, however, witnessed the Friday night attack, which occurred in a busy shopping center. A spokesman for the Anaheim Police Department said police began receiving calls around 8:17 p.m., reporting an assault in progress outside the Carl's Jr. restaurant. When police arrived to the scene, the victim was dead, while the suspect had fled on foot, chased by two civilians. Police apprehended Mr. Ocampo about a quarter-mile from the scene. The homeless killings began on December 20, when the body of the first victim, James McGillivray, 53, was found in Placentia outside a shopping center. The third victim, identified as Paulus Cornelius Smit, 57, was found behind the Yorba Linda library on Dec. 30. Police had not yet confirmed the identity of Friday night's victim, but local residents identified him as John Berry, a Vietnam War veteran who had stayed in the area for years, sometimes sleeping on a bench beside a nearby river bed, or, on rainy nights, in the shopping center where he was killed. A photograph of Mr. Berry appeared in a Los Angeles Times story about the deaths. A makeshift memorial was erected at the spot where he was attacked, where posters filled with remembrances have been left, covering in part the smatterings of blood that were still visible on the concrete wall. Dozens of local residents stopped by to place flowers at the site or to recall a man who they said never asked for money or anything else, and a vigil was planned for Saturday night. "John was a fixture here, a neighbor," said Maria Veruasa, 52, who lives in Yorba Linda. He never asked anyone for money. When you passed by, he would just say "Hi," and "God bless." Sometimes he wouldn't even accept money, so I would leave it discrete on his bicycle seat. Jim Palmer, president of the Orange County Mission, said word of the arrest was just beginning to spread among the homeless here. They were hoping police had the right man, but remained wary for the time being. "We're thankful, obviously, but everyone wants to be real confident that they've caught the right person," Mr. Palmer said. Everyone was feeling a little worn out, because there hadn't been any suspect identified, and we didn't know if this was going to go on for months or when the next person might be killed.
