Pine County authorities have resumed the search for a snowmobiler they believe broke through the ice and was swept down the St. Croix River.
The sheriff's office says it got a 911 call just after 6:30 p.m. Saturday that a snowmobiler had broken through the ice on a remote part of the river. Two other snowmobilers told authorities they were riding on the frozen river in the dark when the victim hit a large patch of open water. He was thrown from his machine and disappeared.
Authorities believe he may have been swept downstream and under the ice pack.
It was too dangerous for responders to enter the water, but they searched on foot, by snowmobile and State Patrol helicopter Saturday night.
