(AP) – Police believe a New Hampshire woman died from exposure in Maine, but they’ll have to wait a while longer before they know for sure. An autopsy was performed Monday in Augusta, Maine, but the state medical examiner’s office couldn’t reach a definitive conclusion about a cause of death for Sarah Rogers. Further studies have been ordered up. Rogers went missing for three agonizing months after leaving her home in Barrington, N.H., on Dec. 13. Her family says she suffered from bipolar disorder and would not have left her husband and 2-year-old son behind if she’d been in the right state of mind. Her body was discovered on Saturday within a half-mile of the spot where her car slid into a snowbank on I-95 in Clinton, Maine.
