SPOKANE, Wash. -

A Montana man was pulled from the Spokane River Thursday morning after the vehicle he was a passenger in crashed into the water.

Crews from the Spokane Fire Department and Spokane Valley Fire Department were called to the T.J. Meenach Bridge at North Pettet Drive on a report of a person in the river calling for help.

The first arriving crews were able to quickly locate a 27-year-old man mid-stream who was hanging onto a branch in swift current. Firefighters were able to pull him from the water, but the man suffered from hypothermia and was very confused. He was taken to the hospital in critical condition.

The man initially said that he and his wife were involved in a vehicle collision where their car had rolled into the river. He was unable to identify the area where the collision occurred and had limited memory of the event.

Firefighters used kayaks and boats to thoroughly search the river for several hours. They also searched the trail system and banks on both sides of the river, looking for the man's wife. The search has been called off due to river and weather conditions and the lack of confirmed information.

As officials continue to investigate what happened, the accounts from the man have varied. Officials have not been able to confirm that a vehicle collision ever occurred, but were able to determine that both the man and his wife were at a local hospital earlier.
