A 54-year-old Burnsville woman died of injuries sustained in a July 22 boat crash in northeast Minnesota, the St. Louis County Sheriff’s Office announced.

Ann Marie Delanghe was one of four people on a boat that struck a dock and boat lift. She was ejected into the water and later died at Essentia St. Mary’s Hospital in Duluth.

The boat’s driver, 50-year-old Brian Deroche, of Duluth, is being investigated for criminal vehicular homicide, the sheriff’s office said.

Darkness, speed and alcohol were factors in the crash, which was reported to dispatchers at 11:16 p.m., the sheriff’s office said. It occurred on Dinham Lake in Ellsberg Township.

Delanghe was rescued from the water by several witnesses on shore and taken to Essentia St. Mary’s with life-threatening injuries. Two other occupants were taken to Essentia Virginia Medical Center.

The boat’s occupants suffered multiple injuries, the sheriff’s office said. The other two occupants were identified as Ernest Delanghe, 57, of Burnsville, and Cindy Deroche, 45, of Duluth.
