A 50-year-old Eden Prairie woman was killed in a boating accident on the Fourth of July, and now the driver of the boat has been arrested.

Brenda Lois Larson was found unresponsive in Cass Lake after she, the 45-year-old driver and a 4-year-old child were thrown from the boat they were on, the Beltrami County Sheriff's Office said in a news release Sunday.

Fishermen passing by rescued the child and the driver, and a short time later – around 4:15 p.m. – Larson was found in the water, unresponsive and not breathing.

She was taken to Cass Lake Hospital, where she was pronounced dead.

Larson was a swim coach for Team Foxjet, based in Eden Prairie, according to the Star Tribune. The program attracts about 400 children per year, and Larson worked with swimmers age 8 and younger, head coach Ann Urschel told the newspaper.

Larson was described as an outgoing person who enjoyed spending time with children and had a passion for swimming.

The driver of the boat was arrested on suspicion of boating while intoxicated. He is being held at the Beltrami County Jail pending formal charges. The child's name has not been released, and the child's relationship to the two adults is not yet clear.

Woodbury teen drowns

Another incident on Minnesota waters was reported over the weekend. A 21-year-old Woodbury man who had gone missing while swimming in a pond in Wells Township, near Faribault, died Saturday, the Faribault Daily News reports.

Officials were called to the pond around 5:15 p.m. Saturday for a report of a missing swimmer. Divers found the man, who has been identified as Devin Nathaniel McCaulley, in 14 feet of water before 6:30 p.m., the newspaper notes.

First responders were unable to revive him, KARE 11 says.

The Hennepin County Medical Examiner is handling the autopsy.
