A Florida man has pleaded not guilty to first-degree murder in the killing of his wife, whose bloody corpse was shown in photos he later posted on Facebook.

Prosecutors also said Wednesday no decision has been made on whether to seek the death penalty for 31-year-old Derek Medina in the Aug. 8 shooting death of 26-year-old Jennifer Alonso. Medina's attorneys have said that he was acting in self-defense and that Alonso was the aggressor.

Medina did not speak during the brief hearing. His plea was entered by one of his attorneys.

Prosecutors say evidence shows that Medina had vowed to kill his wife if she ever attempted to leave him and that she was cowering when she was shot. Medina told detectives he posted the Facebook photos so family could see what had happened.
