Late Thursday night around 11 p.m., a devastating hit-and-run crash occurred near the intersection of 2nd Street and Euclid Avenue just outside the heart of the University of Arizona campus in Tucson. According to the Tucson Police Department, a vehicle struck three pedestrians and fled the scene, leaving two students dead and a third critically injured.
The two students who died have been identified as 19-year-old Sophia Troetel and Josiah Santos. A third student, Katya Castillo‑Mendoza, was also struck and remains hospitalized with serious injuries.
Authorities report that shortly after the crash, the suspected driver — a 19-year-old — was taken into custody. The investigation is ongoing as the scene had been closed for several hours as evidence was gathered and the road reopened afterward.
In response, the University released a sorrowful statement: “The University of Arizona community is deeply saddened by the collision that tragically claimed the lives of Sophia Troetel and Josiah Santos, and seriously injured Katya Castillo-Mendoza. We extend our heartfelt condolences to the families, friends, and all grieving those who lost their lives, and our support to the injured student and their loved ones. The university is providing direct support and resources to students, faculty, and staff affected by this tragic event.”
Friends and peers of Sophia and Josiah described them as bright, kind-hearted young people who brought joy into every space they entered — and their sudden loss has left the campus community reeling. Meanwhile, students and faculty are coming together in support of Katya as she fights to recover. The sentiment across the campus is one of unity in grief and hope for healing.
As the investigation continues, the university is urging students and staff to take advantage of available emotional-health resources. The campus Counseling & Psychological Services (CAPS) is available 24/7 at 520-621-3334, and the university stresses that no one must face the emotional fallout of this tragedy alone.
What began as an ordinary evening suddenly became a traumatic moment for Tucson and the UA community — young lives shortened, a campus in shock, and a reminder of how fragile life can be. As friends gather, memories are shared, tears are shed, and a community stands together, holding space for grief, remembrance, and the hope that Katya will recover.
