A woman missing on northern Minnesota's Iron Range since Saturday was found dead three days later on a hiking trail, and authorities are saying that exposure to the cold appears to have played a role in her death.

The body of Bridgid N. Miller, 43, of Keewatin, was discovered Tuesday evening by members of the Itasca County search and rescue team on the trail near her hometown, according to authorities.

"The weather appears to have been a factor" in her death, according to Keewatin police. Temperatures were below zero about the time she was found. An autopsy was scheduled.

Police say Miller was last seen alive about 2 p.m. Saturday, having left her home on foot, heading west in the direction of Nashwauk, which is about 5 miles away.
