Tin Thanh Nguyen was 31 and worked as a food inspector for the San Bernardino County Department of Health. She was killed on December 2, 2015, while attending a holiday party at the Inland Regional Center in San Bernardino, California, one of 14 people who died in that mass shooting; 21 others were injured. The attack was later classified as an act of terrorism.

Authorities identified the perpetrators as Syed Rizwan Farook and Tashfeen Malik, a married couple who returned to the event with the intent to carry out the attack; both were killed in a shootout with law enforcement later that day. The FBI led the investigation as a counterterrorism case to examine the attackers’ radicalization and any external links.

Tin had been planning to get engaged to her boyfriend, Hansin Trinh, by the end of that year. Her family remembers her as kind and dedicated. If anyone knew Tin or was at the Inland Regional Center that day and can add details about her or the events, please share what is known.
