A jury on Wednesday found a Florida man guilty of second-degree murder after he killed his wife and posted a photo of her blood-spattered body on Facebook.

Jurors rejected the argument that Derek Medina, 33, acted in self-defense when he shot 27-year-old Jennifer Alfonso eight times in August 2013 at their Miami-area residence, according to a circuit court spokeswoman in Miami-Dade County. Prosecutors argued he killed her after an argument in which she threatened to leave him.

Prosecutors said they would seek the maximum sentence for Medina, who faces 25 years to life in prison at a sentencing hearing scheduled for January.
