Both men are set to be arraigned on Wednesday in Santa Clara County Superior Court.
Nationally, while the numbers of most types of homicides have dramatically dropped, domestic violence deaths have remained at historically high levels, according to the district attorney’s office.
The two deaths in June are the third and fourth domestic violence homicides so far this year in San Jose, prosecutors said. There were five domestic violence murders in Santa Clara County during all of 2025.
A few days before the fatal attacks, a man shot his estranged girlfriend at a Kaiser Permanente medical office building in South San Jose.
That shooting, on June 8, left a Watsonville man dead and a woman in critical condition.
Investigators believe it was a murder-suicide attempt with evidence that the motive was domestic violence-related, the district attorney’s office said.
