No criminal charges will be brought against the officers involved in the fatal shooting of a college student at a raucous celebration by Red Sox fans last fall, prosecutors said Monday. "There is no evidence that any officer on Lansdowne Street acted with any intent to commit a crime," Suffolk District Attorney Daniel Conley said at a news conference attended by Boston Police Commissioner Kathleen O'Toole. Victoria Snelgrove, a 21-year-old Emerson College student, was shot in the eye socket with a pepper-spray pellet outside Fenway Park on Oct. 21. Officers were trying to calm the crowd that had filled the streets following Boston's victory over the archrival New York Yankees to win the American League pennant. Police said some of the revelers were throwing bottles, lighting fires and wrecking cars, but Snelgrove was not involved in the rioting. "The fact that the officers were placed in such a chaotic situation ... was a result of poor crowd control planning," Conley said. "The inadequate planning resulted in conditions ... that ultimately set in motion the chain of events that led to Miss Snelgrove's death."
