31 year old Derek Medina had a picture perfect life…. at least online.

The South Miami man posted YouTube videos of himself enjoying sports, authored six online books, with long-winded titles about spirituality, saving the world and hunting ghosts and often shared photos on his Facebook page of his arm tattoos, meals, boating trips and drinks poolside with his wife.

But on Thursday, Medina shocked all of his online friends when he made an announcement on Facebook that he had shot and killed his wife before posting a photo of her twisted, bloodied body lying on a linoleum floor.

The disturbing photo posted on Medina’s Facebook page showed a woman in black tights slumped over on her back. Her knees were bent awkwardly and her cheek and arm were bloody. He included a caption, which read: “RIP Jennifer Alfonso,” and the photo was ‘shared’ amongst his Facebook friends for more than four hours, before the account was finally suspended.

Medina walked into the South Miami police station around noon yesterday (Thursday, August 8, 2013) and spent the evening speaking with homicide detectives about what led up to the shooting death of his 26 year old wife, Jennifer Alfonso.

Alfonso’s 10-year-old daughter from a previous relationship was upstairs at the time of the killing, but was unharmed. The young girl was still at home when officers arrived with a search warrant and they quickly escorted her out of the home, with a blanket wrapped around her, after finding Alfonso’s body.

Medina was charged with first-degree murder late Thursday evening and according to new reports, he is likely to claim self-defense.

His father, Derek Medina Sr., told reporters his son killed Alfonso only after she brandished a knife. In the younger Medina’s Facebook post, he did not mention a knife, but wrote: “My wife was punching me and I’m not going to stand anymore with the abuse so I did what I did. Hope u understand me.”

But according to an arrest report, Medina admitted to investigators he got into an argument with Alfonso. The report said he went upstairs, fished his pistol from a closet and pointed it at Alfonso.

Alfonso yelled she was “leaving him,” according to the report by Detective Jonathan Grossman. Then, Medina — still brandishing the weapon — followed her downstairs to the kitchen, where she grabbed a knife.

Medina said he disarmed Alfonso, put the knife in the drawer, then shot her several times after she began punching and kicking him, the report said. (source)

Alfonso’s former boss at a West Miami-Dade Denny’s told the Miami Herald that the husband was extremely jealous and had hit Alfonso in the past.

“She would be bruised up,” said Amada Cooper, who described Medina as a controlling husband who tried to force her to quit her job as a server because he didn’t want her working nights.

After several violent episodes, another co-worker implored Alfonso to leave him. “He would always come back, begging her … come back,” said Cathy LaBella. “She would say he was going to change. She was in love with him.”

Medina and Alfonso initially married in early 2010 after dating only a few months. The marriage was stormy and friends said he would often kick her out. The two always got back together, however.

Medina and Alfonso were married for a second time in April 2012 and Medina’s father admits they had a rocky relationship.

“They were married for three years, and then they got divorced, and they got remarried last year,” Medina Sr. said. “They always had some problems.” (source)

On his Facebook page, Medina described himself as a property management supervisor and an actor for the Miami-based television drama “Burn Notice,” however he was not listed as a cast member online.

With social networks becoming more and more “social,” we’ve become a society that’s immune to seeing violent photos & videos online.

How much is too much to post on Facebook?

Are you even shocked that the images circulated online for hours?
