In November 2020, Blossom Old Bull was raising three teenagers on the Crow Indian Reservation in Montana. Her youngest son, Braven Glenn, was 17, a good student, dedicated to his basketball team. But he’d become impatient with pandemic restrictions, and his grandmother had just passed away from COVID-19.

One night, Glenn and his mother got in a fight, and he left the house. The next day, Old Bull got a call saying Glenn was killed in a police car chase, that he died in a head-on collision with a train. Old Bull was desperate for details about the accident, but when she went to the police station, she discovered it had shut down without any notice.

Mother Jones reporter Samantha Michaels follows Old Bull’s search for answers about her son’s death and discovers serious lapses in policing on the Crow and other Indian reservations. Old Bull encounters many roadblocks. She files a Freedom of Information Act request for the police report, but her request is denied. As months pass, she still doesn’t have basic information, like which officer chased her son and how he ended up on the train tracks.

Next, Michaels traces the origins of the police force that chased Glenn. It was created by the Crow Nation’s chairman to address a lack of policing on the reservation. Before the new police force was launched, the federal Bureau of Indian Affairs was responsible for policing. But its force was underfunded and understaffed, with only four or five officers patrolling an area nearly the size of Connecticut. The new department was supposed to be a solution, but there were problems from the start. Old Bull learns from a former dispatcher that officers were not properly trained and the department was in chaos.

Nearly three years after Glenn’s death, Michaels is able to obtain information about the accident and share it with Old Bull. Through a FOIA request, Michaels receives official reports about the accident that explain how Glenn ended up on the train tracks. The reports also show how the investigation into the chase was flawed. Old Bull processes the information and grapples with a disturbing fact: The federal government denied her own FOIA request, even though she’s Glenn’s mother, but handed over documents to Michaels, a White reporter with no connection to Glenn. Days later, Michaels brokers a meeting between Old Bull and the former tribal police chief. Old Bull shares how the department’s sudden closure – and the lack of information about her son’s death – affected her family.
