To win a manslaughter conviction, prosecutors must show only that Zimmerman killed without lawful justification. To win a second-degree murder conviction, prosecutors must convince jurors Zimmerman acted with ill will, hatred or spite toward Martin.
Zimmerman faces a maximum prison sentence of life for second-degree murder and 30 years if convicted of manslaughter, due to extra sentencing guidelines for committing a crime with a gun.
The jury of six women started deliberating Friday afternoon. At the time they asked their question about manslaughter Saturday, they had been deliberating for a total of 11 ½ hours over two days. On Friday, they made their first question: a request for a list of all the evidence.
.Jurors wee being sequestered, and their identities are kept anonymous — they are identified only by number.
As jurors deliberated for a second day, there was little understanding between two camps assembled to support Martin and Zimmerman outside the Seminole County Courthouse.
"He deserves some respect and appreciation," Casey David Kole Sr., 66, shouted about the former neighborhood watch leader. "It's a tragedy."
Patricia Dalton, 60, yelled back: "It's a tragedy that could have been avoided!"
Dalton, like most of the 100 or so people at the suburban Orlando courthouse, says she's there in support of the family of Trayvon Martin, the 17-year-old black teen from Miami who Zimmerman fatally shot last year.
The supporters stayed peaceful for most of the day until in the afternoon when sheriff's deputies had to separate a Zimmerman supporter from a pro-Martin demonstrator after a heated exchange. There was no physical contact made and no one was arrested.
The atmosphere quickly cooled down. Two Orlando sisters, dressed in colorful African-print clothing and walking on stilts, sang "Lean on Me" with the crowd as a man strummed a banjo and people waved signs.
"We're just here for peace and love," said stilt walker Bambi Loketo.
Prosecutors and Trayvon Martin's family say Zimmerman profiled Martin because of the teen's race. Those allegations, and a 44-day delay before police arrested Zimmerman, sparked nationwide protests involving leading national civil rights leaders and spurred emotional debates about gun control, self-defense laws, race, and equal justice under the law.
In Saturday's strong Florida sun, some people at the courthouse wore hoodies, as Martin had when he died. One woman lay in the grass, her arms spread, in a re-creation of Martin's death. Those in the smaller pro-Zimmerman camp held small signs, saying things like "We love you George" and "George got hit you must acquit."
Joseph Uy of Longwood was among an even smaller group: the few who said they had no opinion on whether Zimmerman was guilty. He said he came because he was "just curious."
