Cause of Death Revealed After Former College Track Star, 23, Died Months on From Celebrating Master’s Degree

Shelby Daniele, a talented and accomplished former Cal Poly track and field star, tragically passed away from a brain aneurysm at the age of 23. Known for her speed and leadership, Daniele’s sudden death has left her family, friends, and the Cal Poly community in shock.

A Sudden Loss for Cal Poly Athletics

The news comes just months after she earned her master’s degree in agriculture, marking a heartbreaking end to a life full of promise. Daniele competed for the Cal Poly Mustangs for five years, making her mark on the track and leaving behind a lasting legacy. She broke the school’s indoor 200m record last year with a time of 24.69 seconds and also achieved the second-fastest times in both the 60m and 100m events during her tenure.

Remembering Shelby’s Impact on and off the Track

Brian Brandenburg, the father of fellow Cal Poly athlete Eva Brandenburg, shared a heartfelt tribute to Daniele on social media, underscoring the profound influence she had on those around her. “The young lady that was the driving force in Eva’s decision to run track at Cal Poly, Shelby Daniele, passed away… hug your children every time you can and tell them you love them every day,” Brandenburg wrote.

Shelby’s track record is notable, but her character and leadership qualities were equally recognized by her peers and coaches. A six-time All-Big West honoree, two-time Big West champion, and team captain, Shelby embodied the qualities of an exceptional athlete and a role model. Cal Poly Athletics, in a statement, praised her not just for her athletic achievements but for her caring heart and strong leadership. “She cared deeply for those around her, had a remarkable heart, and was a role model for so many,” the statement read. “Shelby was truly one of a kind and will be missed dearly by everyone in the Cal Poly community.”

A Life of Achievement and Dedication

Daniele’s achievements extended far beyond the track. After earning her bachelor’s degree in agriculture in 2023, she went on to obtain her master’s degree in June 2024, completing both with distinction. Her academic success mirrored her determination as an athlete, proving she was not only gifted on the track but also dedicated to her studies. In addition to her athletic accomplishments, Shelby’s spirit of teamwork and compassion left a lasting impression on her teammates. Her school records in the 200m, 60m, and 100m will stand as a testament to her incredible talent, but her memory will live on in the hearts of those who knew her.

Family’s Heartfelt Tributes

In the wake of Shelby’s passing, her sister, Jessica Reichman, shared a poignant tribute on Instagram, expressing her grief and love for her sister. “My worst nightmare happened… my sister, my best friend left Earth to be with God. Too soon and too fast, and I will never understand why… I love you forever, baby girl,” Jessica wrote. The Cal Poly community, her family, and friends continue to mourn the loss of a young woman whose impact stretched far beyond her athletic feats. Shelby Daniele’s legacy will be remembered both on and off the track, leaving behind a void in the hearts of those who loved her.
