WINONA — Searchers continue to scour the Mississippi River but have not found the fourth person who is presumed drowned after an SUV plunged into the icy river.

Search teams used sonar, robots and underwater cameras Wednesday along the shore where the accident happened, but no body was found.

Winona County Sheriff Dave Brand said the search will resume Thursday. Brand said he hopes to bring in cadaver dogs to help with the search.

The missing man is identified as 29-year-old Andrew Kingsbury of La Crosse, Wis.

The body of 28-year-old Blake Overland, of Stewartville, was recovered Monday. The bodies of the driver, 36-year-old Christina Lee Hauser, and one passenger, 30-year-old Mathew Erickson, were found inside the vehicle when it was pulled from the water Sunday.
