UPPER RED LAKE — The bodies of two anglers missing on Upper Red Lake since Saturday were found Monday afternoon after their ATV plunged through the ice in northwestern Minnesota.

According to the Beltrami County sheriff’s office, the bodies of the two missing people were recovered at about 3 p.m. Authorities have not officially identified the bodies, but they have been searching for Melissa Seidenstricker, 29, of Princeton, Minn., and Zeth Knyphausen, 28, of Stacy, Minn.

Seidenstricker and Knyphausen had rented a sleeper cabin at Rogers’ on RED resort on Upper Red Lake. According to the sheriff’s office, the pair had not returned to Shotley Township, about 60 miles north of Bemidji, as previously planned, and a friend called the police.

Chris Freudenberg, who owns the resort, said the anglers’ trailer was found near Mort’s Dock, another resort on Upper Red Lake. Freudenberg said a family member of one of the anglers identified clothing items that belonged to one of the pair.

A Minnesota State Patrol aircraft searched overnight.

Hodapp said searchers found the location Monday morning where the pair fell through the ice.

Just after 2 p.m., the sheriff’s office said they located a submerged ATV that matched the description of the one the pair were using, a pink, camouflage- pattern Polaris Sportsman 500.

Multiple agencies gathered at the resort Monday to assist with the search, with personnel focusing on an area about a mile from shore where they believed the pair fell into the lake. A hole in the ice was discovered and searchers using sonar confirmed the presence of the ATV, the sheriff’s office said. Items located near the open water led rescuers to believe that both Seidenstricker and Knyphausen were in the water.

LOWER RED LAKE SEARCH CONTINUES

Meanwhile, an extensive search is continuing for two missing fishermen on the adjacent Lower Red Lake.

The search for 29-year-old Deland Beaulieu and a 17-year-old boy, who has not been identified by officials, has now reached its fourth week.

The pair, both from Red Lake, Minn., disappeared the afternoon of Nov. 6, when their Red Lake Fisheries boat capsized on Lower Red Lake. The third man on the boat, 32-year-old Dominick Johnson, was able to swim to shore and survived.

According to the Red Lake Police Department, searchers from the Stutsman County (N.D.) Sheriff’s Department and a cadaver dog from Fargo, N.D., returned Monday to help in the search for the missing fishermen.

In the past few weeks, authorities and volunteers have drilled those more than 10,000 holes in the lake and used sonar and underwater camera equipment in predetermined search areas that were mapped out by GPS.

The process of searching under the ice will be greatly enhanced with additional sonar and camera equipment that can be mounted to remote-operated vehicles. The out-of-state teams are expected to search Tuesday and Wednesday, as well. Also, a team from St. Louis County in northeast Minnesota is tentatively expected to come later this week and work through the weekend with six underwater remote-operated vehicles.
