Man charged with killing officer on reservation in Minnesota July 28, 2021 GMT RED LAKE, Minn. (AP) — A man was charged Wednesday in the killing of a Red Lake Nation police officer who was fatally shot while responding to a call to a residence on the tribe’s reservation in northwestern Minnesota. David Donnell Jr., 28, of Redby, was charged in federal court with one count of second-degree murder and four counts of assault with a dangerous weapon in the death of Officer Ryan Bialke. The 37-year-old Bialke was killed Tuesday after he went to Donnell’s home on a report of a suicidal male with children possibly in the residence, according to the Red Lake Department of Public Safety. Federal authorities say Donnell was standing on the porch when officers arrived, then went inside the house.
