The black gunman suspected of killing three white men in a racially motivated attack in Fresno was proud of what he had done and laughed many times as he explained his actions in interviews with police, authorities said Wednesday.
Randalls had been working at the Fashion Fair mall before he chose to take a job at Pacific Gas & Electric Co., Randalls thought it would be a good move for his family's future, his friends said.
During his arrest, Muhammad shouted "Allahu Akbar", but Fresno Police Chief Jerry Dyer said the shootings had "nothing to do with terrorism in spite of the statement he made".
After that moment, Dyer said Muhammad approached two men in PG&E truck. The guard, 25-year-old Carl Williams, was white.
"They were his whole world", his friend, Jonathan Gilbert, said. "Banking on the hopes that American minorities will feel alienated if President Trump handles the subject of race the way he did during his campaign, with divisive language and an attention to white nationalism, black separatism is finding a renewed sense of energy", said the watchdog organization in a January 12 article.
All four gunshot victims on Tuesday were white men, the Sacramento Bee reports, and Chief Dyer said that Mr Muhammad had displayed an anger against white people in Facebook posts.
Muhammad's worldview was thoroughly dominated by race.
Zackary Randalls, a 34-year-old father of two young children, was killed. They scattered, and Muhammad picked the one who was older and appeared heavier: David Jackson, 58, of Fresno.
Pal Eddie Valencia who was with Randalls as life ebbed out of him, said his friend was colour blind. A third was in a local charity's parking lot.
A security guard was shot and killed five days earlier by Muhammad, police say.More news: 'He's Not Stopping!' Car Dragged Along Freeway by Truck for Miles
His criminal history includes gun, drug and theft arrests. As for a motive, police said it had something to do with his longstanding hatred.
Dyer described Muhammad as an extremely callous man.
"This is exclusively based on race", Dyer told reporters.
"If in fact he's lashing out at white people - white males in this case - that would be a hate crime", Fresno Police Chief Jerry Dyer told the Los Angeles Times.
Mark Gassett, 37, was standing on a sidewalk near Catholic Charities. Friday morning, he watched police officers investigate the crime scene and by evening he was in a ravine, where he told police he conducted voodoo rituals for three days.
"First, he said he respected Fresno police officers (and) did not want to force them to shoot him", Dyer said.
Dyer says Muhammad isn't a terrorist but is a racist and described the slayings as a hate crime.
Dyer said Muhammad - born Kori McDonald - also spoke with his mother while in custody and "he told her not to cry, that he's still alive and that his magic is powerful".
Dyer says Muhammad went with officers to the Motel 6, where he is accused of killing unarmed security guard Carl Williams.
Muhammad told police he did not like white people because they are responsible for oppressing Black people and that African Americans and Latinos needed to have their own land with their own laws.
