Very sad. NEW YORKâPolice say a Wal-Mart worker has died after being trampled by a throng of unruly shoppers shortly after the Long Island store opened today. Nassau County police say the 34-year-old worker was taken to a hospital where he was pronounced dead at about 6 a.m., an hour after the store opened. Police also say a 28-year-old pregnant woman was taken to a hospital for observation. Wal-Mart Stores Inc., in Bentonville, Ark., would not confirm the reports of a stampede during the day-after-Thanksgiving bargain hunting, but said a "medical emergency" caused them to close the store.
