A tragic discovery in the Black Hills region leads to second-degree murder charges against a 24-year-old U.S. Air Force member stationed at Ellsworth Air Force Base.

According to Fox News, Quinterius Chappelle, an Airman Basic, has been charged with the murder of 21-year-old Sahela Toka Win Sangrait, a member of the Cheyenne River Sioux Tribe, whose remains were found in a wooded area near the Pennington and Custer County line.

The case began unfolding when Sangrait was reported missing on August 10, 2024, prompting an extensive search effort. Earlier this month, a hiker stumbled upon badly decomposed remains, which authorities later identified as belonging to the Box Elder woman.

Investigators determined that the murder occurred on the military base in August 2024, though specific details about the cause of death remain undisclosed.

Military Service Record and Current Status

Chappelle, who entered military service on April 30, 2019, serves as an aircraft inspection journeyman with the 28th Maintenance Squadron at Ellsworth Air Force Base.

Base officials have maintained strict confidentiality regarding any potential disciplinary history, citing protection under the Privacy Act of 1974.

The accused airman appeared before U.S. Magistrate Judge Daneta L. Wollmann on Monday, where he entered a not-guilty plea to the federal criminal complaint.

Currently held at the Pennington County Jail in Rapid City under U.S. Marshals Service custody, Chappelle awaits further legal proceedings. The trial date remains pending as authorities continue their investigation into the circumstances surrounding Sangrait's death.

Collaborative Law Enforcement Investigation

Multiple agencies joined forces to solve this complex case, demonstrating remarkable cooperation between federal, state, and local law enforcement entities.

The investigation involved the Bureau of Indian Affairs Missing and Murdered Unit, Federal Bureau of Investigation, Air Force Office of Special Investigations, Rapid City Police Department, and the South Dakota Division of Criminal Investigation.

U.S. Attorney for the District of South Dakota, Alison Ramsdell, provided insight into the swift progress of the investigation. She stated:

This charge, filed just 10 days after the victim's remains were discovered, reflects the dogged work of federal, state, and local law enforcement professionals who seamlessly collaborated to run down every lead with absolute expediency and care.

Under the criminal justice system, this charge is merely an accusation, and the defendant is innocent until proven guilty; the facts and evidence in this case will be litigated before a federal judge and jury. At this time, our hearts are with the victim's family and friends, who, after many agonizing months of searching for answers, are now grieving the tragic death of their loved one.

Military Base Response and Support

Col. Derek Oakley, 28th Bomb Wing commander, addressed the situation with gravity and compassion.

He emphasized:

First and foremost, our thoughts and prayers are with the friends and family of Sahela. We hold Airmen accountable for their actions, and if service members are found in violation of military or civilian law, they will be punished.

The base administration has pledged full cooperation with area law enforcement agencies throughout the ongoing investigation. The Bureau of Indian Affairs' Victim Services Program has stepped in to provide essential support to Sangrait's family during this difficult period.

Case Summary and Next Steps

Quinterius Chappelle faces serious allegations in the death of Sahela Toka Win Sangrait, whose disappearance sparked months of searching before the tragic discovery of her remains.

The Airman Basic, stationed at Ellsworth Air Force Base, stands accused of second-degree murder, with authorities alleging the crime occurred on base property in August 2024.

As the case moves through the federal court system, multiple law enforcement agencies continue their collaborative effort to ensure justice while supporting the victim's family through specialized programs. The military base maintains its commitment to accountability while cooperating fully with ongoing investigations.
