Officer Wenjian Liu was at his side.\r      The two cops weren't at their usual precinct -- normally, the pair was assigned to downtown Brooklyn, but they were working a \"critical response\" detail in an area with higher crime, police said. \r      That's where they were slain, ambush-style -- Saturday afternoon as they sat in their patrol car, New York Police Commissioner William Bratton said at an evening news conference.\r      The gunman approached the passenger side of the patrol car and took a shooting stance, witnesses told police. He opened fire several times, striking both officers in the head, Bratton said.\r      They were \"shot and killed with no warning, no provocation,\" Bratton told reporters. \"They were quite simply, assassinated.\"\r      The gunman was found dead in a nearby subway station from a self-inflicted gunshot wound.", "Image Artist": "NYPD"}
