Neil Chamberlain

, a 28-year-old web designer, was crossing Calyer Street in Greenpoint one night in April when a driver sped off McGuinness Boulevard and fatally ran him down, then drove off. Seven months later, police have made no arrests, and Chamberlain's devastated mother says she's frustrated with the NYPD's handling of the investigation. "[The police] don’t seem optimistic," Rachel McCulloch, a finance professor at Brandeis University, tells the Brooklyn Paper. "They identified a car that had damage to it, it had a broken windshield and other damage you might expect if a car collided at some speed with a person, but they didn’t [arrest anyone]." Also frustrating: There was a traffic camera at the intersection, but it wasn't "operational."

Chamberlain's death came as transportation activists were completing a study of reckless driving on McGuinness, a six-lane boulevard. According to a joint study by Transportation Alternatives and Neighbors Allied for Good Growth, drivers violate traffic laws every 17 seconds at Nassau Avenue, where Solange Raulston was killed by a truck driver while riding her bike last December. And over the course of eight hours, volunteers observed drivers running red lights 150 times, talking on cell phones 89 times, and failing to yield to pedestrians 114 times.

McCulloch has joined the groups in calling for new safety measures on McGuinness, though she knows that won't bring her son back. "Six months later, cars are still driving along this stretch at highway speeds, and the driver who ran Neil down and did not stop is still out on the street endangering the safety of others," McCulloch tells BP.
