SANFORD, Fla. — A Florida jury interrupted deliberations on the fate of George Zimmerman for the shooting death of unarmed black teenager Trayvon Martin on Saturday to ask a question about manslaughter, the presiding judge in the case said.

The query for Judge Debra Nelson came about nine hours into the first full day of deliberations in the case. The jury of six women weighed evidence in the Seminole County courthouse for more than three hours on Friday.

The jury must reach a unanimous verdict of second-degree murder, manslaughter or acquittal for Zimmerman, who says he shot the 17-year-old in self-defense.
