From the New York Times:
"On Thursday, the judge, Debra S. Nelson, said the jury would also be able to consider manslaughter as a lesser charge. This charge is typically included in Florida murder cases if either side requests it. Manslaughter with a firearm carries a sentence of up to 30 years in prison."
