UPDATE: (CNN) -- The jurors deciding the fate of George Zimmerman have suspended deliberations for the day, Judge Debra Nelson said around 6 p.m. Friday. They will resume Saturday at 9 a.m. ET.
UPDATE: SANFORD, Fla. (AP) -- A jury is starting deliberations in the murder trial of neighborhood watch volunteer George Zimmerman, who fatally shot 17-year-old Trayvon Martin last year.
Zimmerman is charged with second-degree murder, but the jury will also be allowed to consider manslaughter. Under Florida's laws involving gun crimes, a conviction on either could mean life in prison.
The jurors have been sequestered during the past three weeks. Because there were no eyewitnesses to the shooting, jurors will likely rely heavily on testimony from police, neighbors, friends and family members. The testimony was often conflicting.
Jurors will have to determine whether Zimmerman took the law into his own hands or was in a fight for his life and shot Martin in self-defense.

SANFORD, Fla. (AP) -- George Zimmerman's lawyers made one last attempt Friday to convince a jury the neighborhood watch volunteer shot 17-year-old Trayvon Martin in self-defense, saying the prosecution's case for murder is built on "could've beens" and "maybes."
The jury was expected to begin deliberations as early as Friday afternoon after receiving dueling portraits of Zimmerman: a wannabe cop who took the law into his own hands or a well-meaning volunteer who feared for his life in a struggle with the unarmed teenager who was slamming his head into concrete.
Attorney Mark O'Mara told jurors the burden was on prosecutors, and said they hadn't proven Zimmerman's guilt beyond a reasonable doubt.
"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."
Prosecutor John Guy followed with a rebuttal, accusing Zimmerman of telling "so many lies." He said Martin's last feeling was fear as Zimmerman followed him in a neighborhood on a rainy night 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.
Guy said Zimmerman violated the cornerstone of neighborhood watch volunteer programs, which is to observe and report, not follow a suspect.
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."
Because there were no eyewitnesses, the panel of six women will likely rely heavily on testimony - which was often conflicting - from police, neighbors, friends and family members. They will have to decide who the aggressor was and whether they can determine who was yelling for help on a 911 call that recorded the shooting.
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 dismissed the prosecution's contention that Zimmerman was a "crazy guy" patrolling his townhome complex and "looking for people to harass" when he saw Martin, an unarmed black teenager. O'Mara also 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.
Zimmerman at no point showed ill will, hate or spite during his confrontation with Martin, which is what prosecutors must prove for second-degree murder, O'Mara said.
"That presumption isn't based on any fact whatsoever," O'Mara said.
In contrast, prosecutors argued Zimmerman showed ill will when he whispered profanities to a police dispatcher over his cellphone while following Martin through the neighborhood. They said Zimmerman "profiled" the teenager as a criminal.
O'Mara also told jurors to ask themselves what Martin was doing during the four minutes from when he started running at the urging of a friend he was talking to on a cellphone to when he encountered Zimmerman. Martin was planning his attack instead of going back to the townhome where he was staying, O'Mara said. The defense attorney let four minutes of silence pass to emphasize the amount of time.
"The person who decided ... it was going to be a violent event, it was the guy who decided not to go home when he had a chance to," O'Mara said.
The defense attorney bolstered his arguments
