Former Cal Poly track and field star Shelby Daniele tragically passed away from a brain aneurysm, according to reports. The 23-year-old athlete’s death occurred on September 25. Recently, Brian Brandenburg, the father of a fellow Cal Poly athlete, revealed Daniele’s cause of d**th in a Facebook tribute post.

In the post, Brandenburg paid tribute to his two daughters, Tori and Eva, on National Daughters Day. He shared that Daniele had been a significant influence on Eva’s decision to join Cal Poly’s track team, describing Daniele as the “driving force” behind her choice to run for the program.

According to The Mayo Clinic A brain aneurysm (AN-yoo-riz-um) “is a bulge or ballooning in a bl0*d vessel in the brain. An aneurysm often looks like a berry hanging on a stem. Brain aneurysms are common. But most brain aneurysms aren’t serious, especially if they’re small. Most brain aneurysms don’t rupture. However, a ruptured aneurysm quickly becomes life-threatening and requires medical treatment right away.”
