The South Dakota legal landscape undergoes a significant twist as the state Supreme Court grants a new trial for Dion Bordeaux, convicted of the first-degree murder of Jeanette Jumping Eagle. This decision emerges after a crucial review of the character evidence used in the initial 2023 trial, reflecting the complex legal intricacies within the state.
Jeanette Jumping Eagle, a member of the vibrant community in Rapid City, was tragically found dead from a gunshot wound to the head on New Year’s Day 2020. Her death sent ripples through the local community, renowned for its cultural diversity and historical significance amidst the scenic beauty of the Black Hills.
The original verdict, delivered in 2023, determined Bordeaux’s guilt, marking a poignant moment within South Dakota’s judicial history. However, questions soon arose regarding the fairness of trial procedures, launching an appeal in July of the previous year. This appeal contended the inadmissibility of a prior guilty plea in the murder case—a pivotal point that dramatically swayed the recent court ruling.
In 2019, Bordeaux was previously convicted for a separate incident involving the stabbing of a man. He subsequently pleaded guilty to assault in June 2020. This conviction became a contentious piece of character evidence in the subsequent murder trial, challenging the norms of criminal procedures within the state.
Character evidence, rarely permissible unless directly relevant, played a crucial role in the prosecution’s strategy. Their argument emphasized the supposed similarity between the incidents, both involving intoxicants and acts of violence within personal relationships—an angle reflecting familiar challenges in the state’s legal context.
All five justices of South Dakota’s Supreme Court unanimously agreed that the trial judge wrongly allowed this character evidence. This landmark judgment underscored the intricacies of South Dakota’s legal system and the delicate balance of ensuring fair trials, consistent with the state’s dedication to justice.

Despite the unanimous agreement on the evidence, the decision to grant a new trial was narrowly split, with a 3-2 vote paving the way for retrial. This demonstrates the importance of procedural justice and the state’s commitment to upholding the integrity of its judicial processes.
For the people of South Dakota, closely knit through shared histories and community values, the case of Dion Bordeaux serves as a reflective moment on the broader themes of justice and community resilience. Known for its beautiful landscapes and the rich tapestry of Native American traditions, South Dakota sets a powerful example of judicial diligence and cultural respect.
As Rapid City continues to process this development, a renewed trial promises to delve deeper into the facts surrounding the incident—an undertaking vital to ensuring accuracy and fairness in judicial procedures. The decision not only influences the legal resolutions of the present but also shapes future judicial practices amid growing concerns about the use of character evidence in trials.
