"He figured he can restart his life, but he's really upset at the system," the elder Goulet said. "He already has anger management issues so everything was coming to a head."
Until last fall, a neighbor said the twin brothers lived for at least a year in a brown-shingled house on a quiet street in Berkeley."
Alicia Morrison said she and her husband lived in the apartment just below the brothers and called the police in September when they got into a violent fight.
"I didn't think it was an everyday fight. It sounded like one of them was going to get killed ," she said. "They would throw each other down on the ground and they had two dogs upstairs who sounded like they were really scared."
She said Jeremy left before the police arrived on that occasion.
She said neighbors had called police for the same reason before, and a few days after Morrison called the police she said they came by the apartment again because Jeremy Goulet's girlfriend had been screaming.
"Every time the police were called they acted like it was no big deal," she said.
The shootout occurred about 75 miles south of San Francisco in the town with world-class surf spots, historic downtown with bookstores and coffee shops, and the University of California, Santa Cruz.
Its boardwalk is a major summer draw for tourists hoping to escape inland heat or enjoy a classic California experience.
Lately, the city of 60,000 people had seen a spike in assaults that community leaders had planned to address Tuesday during a downtown rally that was cancelled along with a City Council meeting by teary-eyed leaders after they learned of the deaths.
"There aren't words to describe this horrific tragedy," said Police Chief Kevin Vogel.
The mid-afternoon shooting about a mile from the boardwalk prompted the lockdown of two schools and an automated police call to nearby residents, warning them to stay locked inside.
Jeffery Goulet, the suspect's twin brother, released a statement Wednesday saying his family was deeply saddened by the events in Santa Cruz.
"We would also like to extend our deepest sympathies to the families of Sgt. Loran Baker and Detective Elizabeth Butler," it said.
Baker, a 28-year veteran of the force, and Butler, a 10-year veteran, had been shot at and called for backup before arriving officers found Goulet, who was killed after opening fire on them, authorities said.
Baker's son, Adam Baker, served as a community service officer, and father and son had mailboxes side-by-side at the Police Department.
Butler came to Santa Cruz to study at the university and stayed, the newspaper said.
"You have to be a people person down here," she told the newspaper in a 2005 interview. "I really do know people's names."
