SANFORD, Fla. -- With police and civic leaders urging calm, a jury began deliberating George Zimmerman's fate Friday after hearing dueling portraits of the neighborhood watch captain: a cop wannabe who took the law into his own hands or a well-meaning volunteer who shot Trayvon Martin because he feared for his life.
As the jury got the slaying case, police in this Orlando suburb went on national television to plead for peace in Sanford and across the country, no matter what the verdict.
"There is no party in this case who wants to see any violence," Seminole County Sheriff Don Eslinger said.
During closing arguments, Zimmerman's lawyers put a concrete slab and two life-size cardboard cutouts in front of the jury box in one last attempt to convince the panel that Zimmerman shot the unarmed black 17-year-old in self-defense while his head was being slammed against the pavement.
Attorney Mark O'Mara used the slab to make the point that it could serve as a weapon. He showed the cutouts of Zimmerman and Martin to demonstrate that the teenager was considerably taller. And he displayed a computer-animated depiction of the fight based on Zimmerman's account.
He said prosecutors hadn't met their burden of proving Zimmerman's guilt beyond a reasonable doubt. Instead, he said, the case was built on "could've beens" and "maybes." "If it hasn't been proven, it's just not there," O'Mara said. "You can't fill in the gaps. You can't connect the dots. You're not allowed to."
In a rebuttal, prosecutor John Guy accused Zimmerman of telling "so many lies." He said Martin's last emotion was fear as Zimmerman followed him through the gated town house community on the rainy night of Feb. 26, 2012.
"Isn't that every child's worst nightmare, to be followed on the way home in the dark by a stranger?" Guy said. "Isn't that every child's worst fear?"
One juror, a young woman, appeared to wipe away a tear as Guy said nothing would ever bring back Martin.
The sequestered jury of six women -- all but one of them white -- will have to sort through a lot of conflicting testimony from police, neighbors, friends and family members.
Witnesses gave differing accounts of who was on top during the struggle, and Martin's parents and Zimmerman's parents both claimed that the voice heard screaming for help in the background of a 911 call was their son's.
Jurors deliberated for 31/2 hours when they decided to stop Friday evening. They will resume deliberations this morning.
Zimmerman, 29, is charged with second-degree murder, but the jury will also be allowed to consider manslaughter. Under Florida's laws involving gun crimes, manslaughter could end up carrying a penalty as heavy as the one for second-degree murder: life in prison.
O'Mara disputed prosecutors' claim that Zimmerman snapped when he saw Martin because there had been a rash of break-ins in the neighborhood, mostly by young black men. Prosecutors argued Zimmerman "profiled" the teenager as a criminal.
Zimmerman's account of how he grabbed his gun from his holster at his waist as Martin straddled him is physically impossible, Guy said.
"The defendant didn't shoot Trayvon Martin because he had to; he shot him because he wanted to," Guy said. "That's the bottom line."
About a dozen protesters, most of them from outside central Florida, gathered outside the courthouse as the jury deliberated. Martin supporters outnumbered those for Zimmerman.
