A Massachusetts college student was killed last week by a pellet that a policeman fired into a crowd of raucous baseball fans. Eighty thousand people had spilled into Boston streets to celebrate after the Boston Red Sox beat the New York Yankees to qualify for the World Series. Police fired supposedly nonlethal pellets filled with pepper spray to keep the melee under control. One of the projectiles hit Victoria Snelgrove, 21, in the eye, and she died hours later. Police promised an investigation, but Police Commissioner Kathleen OToole blamed punks for provoking officers. Snelgroves father said that was no excuse. She went to celebrate with friends, Rick Snelgrove said. She was a bystander.
