MIAMI (Reuters) - A Florida man convicted of second-degree murder after killing his wife and posting a photo of her blood-spattered body on Facebook was sentenced to life in prison on Friday.

Derek Medina, 33, wrote on Facebook shortly before turning himself in over the August 2013 shooting: "I'm going to prison or death sentence for killing my wife."

"You foretold your future," said Florida circuit court Judge Yvonne Colodny before handing down the sentence.

A jury late last year rejected his contention that he was acting in self-defense when he killed his wife, 27-year-old Jennifer Alfonso, in the kitchen of their Miami-area residence.
