Sentencing on the second-degree murder charge is set for early next year

(CNN) A Florida man who posted a photograph of his wife's body on Facebook was found guilty Wednesday of second-degree murder.

Derek Medina of South Miami was accused of shooting his wife, Jennifer Alonso, in August 2013. After he killed her, authorities say, he posted a picture of her body on his Facebook page with a note.
