A worker was killed in the crush Friday after a throng of shoppers eager for bargains burst through the doors at a suburban Wal-Mart, authorities said. At least four other people were injured, and the store in Valley Stream on New York's Long Island was closed. Wal-Mart Stores Inc. in Bentonville, Arkansas, called the incident a "tragic situation" and said the employee came from a temporary agency and was doing maintenance work at the store. "He was bum-rushed by 200 people," co-worker Jimmy Overby, 43, told the Daily News. "They took the doors off the hinges. He was trampled and killed in front of me. They took me down too. ... I literally had to fight people off my back." Nassau County police said the 34-year-old worker was taken to a hospital where he was pronounced dead at about 6 a.m. The man's name was not released and the cause of death was not immediately known.
