Hays woman pleads guilty to assault on Fort Belknap Indian Reservation

GREAT FALLS - A Hays woman accused of an assault on the Fort Belknap Indian Reservation admitted to charges yesterday, U.S. Attorney Kurt Alme said.

The defendant, Heavenlee Drewann Sears, 24, pleaded guilty to one count of assault resulting in serious bodily injury. Sears faces a term of imprisonment of 10 years, a $250,000 fine, and 3 years of supervised release.

Chief U.S. District Judge Brian M. Morris presided and will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors. Sentencing was set for March 12, 2026. Sears was detained pending further proceedings.

The government alleged in court documents that on the evening of September 29, 2023, the defendant and a co-defendant were driving around on the Fort Belknap reservation and drinking beer. Late in the night, the two went to a bar to buy more alcohol before driving to John Doe’s home.

When Sears and her co-defendant arrived at Doe’s house, they were highly intoxicated, and they beat him. Sears hit him multiple times on the head with a peppermint schnapps bottle. Around 6:00 a.m. on September 30, Sears called a family member to say something was wrong with Doe. While they waited for the family member to arrive, Sears analyzed the bloody footprints around Doe and realized she had made the prints. Sears also called 911.

Doe was taken to Fort Belknap Indian Health Services. He was unresponsive and breathing erratically. His admission records state his ears and face were bruised and swollen, his nose was lacerated, his upper lip was lacerated, and there was a human bite mark on his forehead. There were also bite marks to his left wrist and left upper chest. After he was intubated, Doe was life flighted to a higher level of care.

On September 30, 2023, Sears spoke to law enforcement. She reported Doe was drinking earlier with a friend. Sears first told law enforcement she blacked out and when she “came to,” she found Doe on the ground, with lots of blood around him and blood coming out of his mouth. She told law enforcement she called a family member and then called 911. Sears said she didn’t remember what happened to Doe.

When officers told her it seemed like she remembered more than she said she did Sears started to cry. She said she “probably” hit him because she was drunk and has a temper. Sears said she thought she might have hit Doe with the empty peppermint schnapps bottle. When asked if she hit him, she nodded. When asked if she hit him with the bottle, she again nodded. Sears did not know how many times she hit Doe, but she hit him more than once. The second time she hit him, Doe fell to the ground.

On October 18, 2023, Doe was admitted to the Long-Term Care Hospital in Billings, Montana. He was diagnosed with traumatic subarachnoid hemorrhage. Doe was largely unresponsive to stimuli and completely nonverbal due to his traumatic brain injury. Doe died on December 11, 2023.

The U.S. Attorney’s Office prosecuted the case. The FBI and Fort Belknap Law Enforcement Services conducted the investigation.

This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. On May 26, 2021, the Department launched a violent crime reduction strategy strengthening PSN based on these core principles: fostering trust and legitimacy in our communities, supporting community-based organizations that help prevent violence from occurring in the first place, setting focused and strategic enforcement priorities, and measuring the results.
