On Thursday afternoon, 24 hours after two shooters began firing into the crowd at a holiday party in San Bernardino, California, ultimately killing 14 people and wounding 21 more, some victims of the massacre were identified. They included Sierra Clayborn, a San Bernardino County employee, who was confirmed to be deceased by a relative who spoke to People magazine. Clayborn was originally from L.A., according to her Facebook profile, and worked in the county's health department.

According to Clayborn's LinkedIn profile, she served as an environmental health specialist, and had done for the county for three years. She had studied biochemistry at the University of California, Riverside. "Am currently working in the field of Community Environmental Health, making a difference daily by protecting people where they live, work and play," she wrote on her LinkedIn profile.

After news of the shooting broke, people took to Clayborn's Facebook page to express fear that she may have been one of the victims. Hours later, they learned they she had been. "RIP Baby sis I love you more than you ever knew," People reports Clayborn's sister, Tamishia, wrote on her Facebook page.

Her last profile photo had been recently changed to reflect her support for victims of November's Paris attacks.
