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.

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.”
