Construction crews working to restore a baseball field Saturday stumbled on an archaeological mystery --- human bones believed to have been buried at the field 300 years ago.

State archeologists rushed to Sturges Park off Mill Plain Road. According to historians, the ballpark is the former site of an 18th-century church and cemetery. Experts say the bones, including a lower jaw, hip bone and leg and arm bones are more than likely from a body buried there 300 years ago. Archeologists are examining wood that they believe might be part of an old coffin.

The Fairfield Historical Society looked through its records and found that the church moved in 1738 to another site and the burial grounds were forgotten by most people. Archaeologists say it?s not uncommon for gravesites to remain behind. The archaeologists say they hope to identify whose remains were uncovered.Related information: Plan to build baseball diamond in Fairfield may face 300-year-old obstacle
