Witness 9 was then asked whether there was anything else she wanted to discuss about Zimmerman.
"I was afraid that he may have done something because (Martin) was black," she said. "Growing up, him and his family have always made statements that they don't like black people if they don't act like white people."
She told investigators that Zimmerman's mother, while talking about President Barack Obama, said she didn't like him because, "I am a racist."
Witness 9, however, didn't provide any detailed instances about George Zimmerman being a racist.
"I can't remember anything, but that's just a known thing that that's how his family feels," she said.
More than 100 jailhouse phone calls made by Zimmerman, the neighborhood watch leader charged with murder in the death of Martin, were also released Monday by the state.
In the calls, Zimmerman speaks with Terry Jones, a Gainesville pastor who sparked international outrage when he burned Korans, and his wife, Shellie.
Zimmerman, 28, is charged with second-degree murder in the Feb. 26 shooting death of Martin, a 17-year-old who was unarmed while waking through a gated Sanford neighborhood. Zimmerman has pleaded not guilty, claiming self-defense.
On Friday, Zimmerman filed a motion to disqualify Judge Kenneth Lester, whom Zimmerman claims showed bias against him in his recent bond hearing ruling.
The State Attorney's Office released a statement Friday afternoon objecting to Zimmerman's motion.
On July 6, Zimmerman bonded out of jail for a second time after posting a $1 million bond.
In a scathing order, Lester restricted Zimmerman's travel to within Seminole County, subjected him to a curfew, barred him from the local airport and required him to wear an electronic monitoring device. He is also not allowed to apply for a passport or to drink alcohol.
An initial bond of $150,000 was revoked last month after Lester learned that Zimmerman and his wife, Shellie, had failed to disclose more than $150,000 in donations from the public.
In April, Seminole Circuit Judge Jessica Recksiedler approved a motion to disqualify herself from the case and Lester took her place.
O'Mara had asked Recksiedler to step aside because her husband is a law partner of Mark NeJame, an Orlando lawyer and CNN legal analyst. Recksiedler concluded that the arguments individually were "legally insufficient" to force her recusal, but the "totality of the circumstances" made her decide to hand the case to another judge.
Zimmerman was not arrested until 44 days after the shooting because Sanford police said there was not enough evidence to disprove Zimmerman's claims of self-defense.
Florida's "stand your ground" law, which allows someone to use lethal force if they feel their life is in danger, came under fire and protests were launched across the country.
Gov. Rick Scott appointed Angela Corey as a special prosecutor, and she charged Zimmerman with second-degree murder.
