EAST MISSOULA, Mont. -

The Missoula County Sheriff's Department reports it's confident that no one is inside the vehicle submerged in the Clark Fork River near East Missoula. Search and rescue workers broke the windows of the dark blue pickup and probed for occupants, but didn't find any.

The pickup was discovered near the Sharon Fishing Access site Monday evening. Investigators said the pickup does not match that of a missing North Dakota woman's vehicle.

Florence Dumontet was last seen with her black pickup in Butte last October. Crews plan to retrieve the blue pickup in the river late Tuesday afternoon.

"One of the options is to place air bags underneath the vehicle," said sheriff's department spokesman Jason Johnson, "rise it up off the bottom and then maneuver it to the Sharon Fishing Access site."
