Benjamin said she and her husband contributed $2,500 to George Zimmerman legal defense fund, plus clothing.
During cross-examination, de la Rionda had Benjamin examine Zimmerman's voice on his call reporting the and if Zimmerman was outside or winded during the non-emergency call.
Benjamin said that profanity doesn't always indicate anger, as de la Rionda raised his voice demonstrating Zimmerman's words on the call.
The defense then called Benjamin's husband, John Donnelly. Donnelly said as a Vietnam War veteran he was able to develop ability to distinguish screaming voices.
O'Mara then played the 911 call with the screaming in the background for Donnelly.
"There's absolutely no doubt in my mind that's George Zimmerman," Donnelly said, wiping tears from his eyes on the stand.
The prosecution said it has an issue to discuss with the judge, likely over Donnelly not listening to screams until after deposition.
Donnelly testified he donated $4,700 in cash and clothes to Zimmerman and his defense fund.
"I think of him as a son," Donnelly said.
Also on Monday, the state filed a motion to block the defense from presenting a computer-animated reenactment showing the altercation between Martin and Zimmerman to the jury, citing speculation, incompleteness and late discovery.
The defense called its first two witnesses Friday after prosecutors rested and Judge Debra S. Nelson denied a request for acquittal.
Zimmerman's mother and uncle testified that it was Zimmerman screaming for help on a 911 call that captured the fight between Zimmerman and 17-year-old Trayvon Martin.
Zimmerman, 29, has pleaded not guilty to second-degree murder for fatally shooting Martin, claiming self-defense.
It's still uncertain whether Zimmerman will testify.
Jurors already have heard his account through videotaped police interviews played in court.
