Brianna Kupfer's family and friends gather for what would have been the slain woman's 25th birthday

Kupfer's family started the Brianna Kupfer Foundation to champion causes she cared about

Family and friends of Brianna Kupfer hosted a charity run for the slain UCLA grad student on Saturday, nearly three months after police say a homeless man walked into the Los Angeles furniture store where she was working alone and fatally stabbed her in a "random" attack. 

People gathered at the Brentwood school track to run, do yoga, and dance on what would have been Kupfer's 25th birthday. Proceeds from the event will go to the newly established Brianna Kupfer Foundation, which will help causes that she cared about. 

"We will be championing causes dear to Brianna, such as environmental and social justice issues, as well as honoring victims like Brianna through the protection of women and social betterment," Mikaela Kupfer, Brianna's sister, wrote on the foundation's website.

The 31-year-old has a lengthy criminal history and was out on a $50,000 bond for allegedly shooting a flare gun into someone's car with a toddler inside in South Carolina three years ago. 

He was charged with discharging a firearm at an occupied vehicle, but the case is still pending due to a 1,330-case COVID-19 backlog in Charleston County.
