California police have arrested a former University of California Davis student for a string of stabbings near the campus west of Sacramento.

Davis Police Chief Darren Pytel said that Carlos Dominguez, 21, had been charged with two counts of murder and one count of attempted murder, KOVR reported.

Dominguez had attended the university since 2020, studying biological sciences, until April 25, when he formally failed out, the school said. That was two days before the first stabbing.

The body of 50-year-old David Breaux was found with multiple stab wounds on April 27 in a local park. Two days later, another man, identified as UC Davis student Karim Abou-Najm, 20, was found dead in a different park north of campus. Abou-Najm had been biking home from an academic awards ceremony at the time, and investigators said that his attacker fled on his bicycle.

Davis Deputy Chief Todd Henry said that a witness saw the stabbing and the attacker fleeing the scene. Police launched a search but didn’t find him, although they found the victim’s bike outside the park.

On Monday, police found a critically wounded woman, identified as 65-year-old Kimberlee Guillory, at a homeless encampment near campus, Pytel said. The attacker had apparently slashed open her tent and stabbed her multiple times. Guillory was treated first at the scene, then taken to a hospital. Pytel said Thursday she is “recovering.”

Dominguez was taken into custody Wednesday for questioning after multiple calls to police reported seeing a person who matched the suspect’s description in Sycamore Park, where Abou-Najm was killed. He was initially arrested early Thursday morning for possessing a large knife. Thursday afternoon, he was charged with killing Abou-Najm and Breaux and injuring Guillory.

Pytel said Dominguez was wearing the same clothes when he was taken into custody on Wednesday that he had been wearing Monday when he attacked Guillory.

“That’s highly unusual,” the chief said.

Pytel said that a search of Dominguez’s residence provided “significant and related evidence,” as did interviews with other people who live at the residence.

The chief said investigators are still looking for a motive and said it’s not clear if Dominguez knew any of the victims.
