FOLLOW-UPEmail
There is relief in knowing the alleged perpetrator of these senseless and violent acts is now in custody. We can all breathe a little easier and begin to process the pain, fear, and sorrow we collectively experienced in the past week.
Verbatim quote from UC Davis Chancellor Gary S. May's campuswide message issued Thursday May 4, 2023, after the arrest of Carlos Reales Dominguez
The chancellor's framing ('breathe a little easier') is unusually personal and explicitly emotional language for a UC chancellor's communication
The phrase 'collectively experienced' reflects the institutional posture that the trauma extended beyond direct victims to the entire community
Context

Background

Between April 27 and May 3, 2023, the city of Davis, California, was gripped by a series of three random stabbing attacks that killed two people and critically injured a third. The first victim, David Henry Breaux, 50, a homeless man, was found fatally stabbed on a bench in Central Park on the morning of April 27. Two days later, UC Davis senior Karim Abou Najm, 20, a computer science major, was stabbed to death at Sycamore Park. On May 1, Kimberlee Guillory, 64, a homeless woman, was stabbed through her tent at an encampment at 2nd and L Street shortly before midnight; she survived and called 911. Following the third stabbing, the city issued a shelter-in-place order that was lifted the next morning at 5:17 AM PDT. UC Davis canceled all evening in-person classes and moved them to virtual instruction. On May 3, police arrested Carlos Reales Dominguez, 21, a former UC Davis student who had been academically dismissed on April 25, just two days before the first killing. Dominguez was charged with two counts of murder and one count of attempted murder. In August 2023, he was found not competent to stand trial and was transferred to a state hospital; his competency was restored in December 2023. At his 2025 trial he admitted committing the stabbings but pleaded not guilty by reason of insanity, testifying that he has schizophrenia and attacked the victims believing they were shapeshifting figures. In June 2025 the jury found him not guilty of first-degree murder and deadlocked on second-degree murder, and a mistrial was declared. A retrial on the remaining second-degree murder and attempted-murder counts began in May 2026; as of July 2026 it was in closing arguments with no verdict, and the judge found a Racial Justice Act violation in the prosecution's closing argument.
