Derek Medina posted an image on Facebook that showed his wife's leggings-clad body slumped backwards on the floor in what appears to be the couple's kitchen. Her face and left arm are covered in blood. According to an arrest affidavit by Miami-Dade Police, Medina told investigators he and Alfonso had a verbal dispute around 10:00 a.m., during which he grabbed a gun from a closet and pointed it at his wife. She reportedly told Medina she was leaving him before the dispute moved downstairs. There, Medina told police, Alfonso began punching him. He retrieved the gun from upstairs and again confronted his wife, prompting her to pick up a knife. He told detectives that when he took the knife away, his wife began hitting him again, at which point he shot her several times.
