(CNN) The fate of George Zimmerman is now in the hands of a six-person jury.
The jury deliberated for several hours Friday before recessing until Saturday.
Zimmerman is accused of second-degree murder for killing the 17-year-old Trayvon Martin on February 26, 2012.
He has always acknowledged killing Martin. The question has been why.
Observers have said prosecutors have not proved their case beyond a reasonable doubt while others think the all female jury could want to make Zimmerman want to spend some time in jail.
“It is up to you decide which evidence is reliable,” Judge Debra Nelson told the jurors, adding they should “use your common sense” to determine what evidence is reliable and what is not.
She told the jury that Zimmerman exercised his legal right not to testify, and they can not “view this as an admission of guilt.”
“It is not necessary for George Zimmerman to prove anything,” Nelson said.
Police in Sanford, Florida, and elsewhere steeled for the possibility of violent reactions to the verdict, while the Rev. Jesse Jackson Jr. called for a calm response to the jury’s decision, no matter what it is.
