The Yolo County District Attorney’s office revealed in a Thursday court hearing a new theory in the case against Carlos Reales Dominguez.

The former UC Davis student is accused of a stabbing spree in Davis, killing two men and severely injuring an unhoused woman in April of 2023. Fear took hold of the community while police searched for the killer.

David Breaux, 50, known as “The Compassion Guy,” was the first victim. Karim Abou Najm, 21, who was about to graduate from UC Davis, was also killed. Kimberly Guillory survived her stab wounds.

Dominguez, wearing a striped jail jumpsuit and buzzcut, appeared in court for a motion hearing regarding his mental state.

Judge Samuel McAdam acknowledged the introduction of the state’s new theory.

“This is an entirely new theory for the people?” he asked.

Dominguez’s first trial in June ended in a mistrial when the jury could not reach a verdict.

Assistant Chief Deputy District Attorney David Wilson argued for the motion to have their psychiatrist examine Dominguez to see if he suffered from cannabis-induced psychosis.

“The defendant was purchasing high THC value, meaning above 10% products, for months, if not years, prior to the events in question. Those high THC materials lead to psychosis,” he said.

However, Dominguez’s defense maintains that he committed the stabbings due to severely untreated schizophrenia, experiencing his first psychotic break during the attacks.

“No less than eight psychologists and psychiatrists have diagnosed Mr. Dominguez as suffering from schizophrenia. He still suffers from the negative symptoms of schizophrenia, which of course saw throughout the trial, which he still suffers from to this day,” said Dan Hutchinson.

The prosecution is now questioning whether marijuana use caused the schizophrenia, and said the theory was ignored during the first trial. “In my review of the 8,000 pages of discovery and much of the reports is that it was touched upon, but more or less ignored,” said Wilson.

Wilson told the judge he didn’t know why the theory was ignored.

The judge denied the motion for further evaluation.

“The defendant has been treated for schizophrenia for over two years. He’s been in custody, and he’s been on psychotropic medication as part of his treatment. His circumstances for an evaluation now are dramatically different,” said McAdam.

McAdam said the prosecution can call their expert as a witness during the second trial and question him about the theory.

The judge also emphasized the need for the trial to proceed in a timely manner, with the second trial scheduled to start on January 20. Preparations are underway to send out 1,000 notices to potential jurors.

The judge highlighted the importance of justice for the victims, the victims’ families, and the defendant.
