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.
Jurors deliberated for three and a half hours when they decided to stop Friday evening. About two hours into their discussions, they asked for a list of the evidence. They will resume deliberations Saturday morning.
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.
