A South Miami, Florida, man has been charged with murder after allegedly killing his wife and posting a confession and photo of her blood-stained body on Facebook.
Derek Medina, 31, drove to tell his family what he'd done, then turned himself into police shortly after posting the picture and note, which read: "Im going to prison or death sentence for killing my wife love you guys miss you guys takecare Facebook people you will see me in the news."
New surveillance video of the killing and excerpts from the victim's diary have been released. Does the new evidence show that Medina snapped? Or did he plan to kill his wife all along? Our experts present both sides of the story and debate what could have led to this tragic incident.
