Yvette Alexandra Velasco, 27, was killed on December 2, 2015, during the mass shooting at the Inland Regional Center in San Bernardino. A resident of Fontana, California, she worked for the San Bernardino County Public Health Department and was one of 14 people killed in the attack. Family members described her as intelligent, motivated, and full of life.

The shooting was carried out by Syed Rizwan Farook and Tashfeen Malik, a married couple who opened fire at a holiday party with rifles and handguns. Law enforcement later engaged the attackers in a shootout in which both were killed. Investigators determined the attack was motivated by extremist ideology and that the couple had planned the assault and tried to destroy evidence, including digital devices.

Yvette’s death is one of several that underscored the human cost of that day and prompted wide-ranging investigations and debate about security and counter-terrorism.
