Boston ? Federal prosecutors have accused a couple of intentionally eating glass to support fraudulent insurance claims against restaurants, hotels and grocery stores.

Ronald and Mary Evano filed claims in Massachusetts, the District of Columbia and three other states claiming that they had eaten glass found in their food at the establishments. In at least some cases, they intentionally ate glass that did not come from food they had bought, prosecutors said. Mary Evano is still being sought.

In 1997, Mary Evano went to a hospital claiming to have eaten glass at a Boston restaurant, prosecutors said. The couple settled with the restaurant’s insurer for $22,000, according to an indictment made public Friday.
