7-18-12  --  A criminal investigation into needles being found in turkey sandwiches was prompted by three Minnesotans aboard two Delta Air Lines flights from Amsterdam on Sunday.  Jim Tonjes  of Plymouth and Jack Drogt of St. Paul say they found inch-long sewing-like needles in sandwiches on their flight to Minneapolis-St. Paul International.  Tonjes said he bit on the needle, which punctured the roof of his mouth.  Drogt's 16-year-old son William, who was on a flight to Atlanta, also found a needle in his turkey sandwich.  The sandwiches were made by a catering company in the Netherlands.
