(CNN) — People confess to a lot of things on Facebook: their frustrations, bad habits, secret longings and new loves. A Florida man allegedly confessed to a slaying Thursday on the social media website, that of his wife, whom he told police he shot dead in their kitchen.
Derek Medina, 31, posted a picture of her blood-stained body — collapsed and contorted on the floor in the corner — to his Facebook feed with a note.
“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.”
Medina, who lives in South Miami, drove to see his family, to tell them what he did. Then he turned himself in to police, according to his arrest affidavit.
Facebook friends commented on the photo in shock.
“That is my friend there.”
“What happened???? derek.”
Other Facebook users reacted with disgust to the posting of the picture of his wife’s corpse. She was 26.
“this is crazy omg … guy kills his wife post pic in facebook.”
The disgust did not prevent the commenters from sharing Medina’s photo. Again and again.
Her gruesome likeness stayed online and was passed along for at least five hours, until Facebook was notified of the content. Employees removed the picture and disabled Medina’s page and that of his deceased wife, according to Facebook.
In his note, Medina accused his wife of abusing him and asked his friends for their understanding for what he did to her because of it.
The police report with his confession cast a more detailed light on the course of events.
This was Medina’s account to Miami Dade police:
He and his wife argued. He pulled a gun on her. She threatened to leave him. He put the gun away and followed her. She unloaded a volley of punches on him. He fetched the gun again. She pulled a knife. He wrestled it out of her hands. She punched him again.
Then he shot her “multiple times.”
He felt certain she was dead. He did not call 911, the affidavit states. He changed clothes, and after seeing his family, went to a police station and began the process of confessing.
After he gave police his address, they drove to the scene, where they found the body.
The couple’s 10-year-old daughter was also still in the house, police said. She was physically “unharmed.”
Hours before the slaying, Medina posted a picture of the three of them having dinner together outdoors at a marina.
They were all smiling.
