Messages Show Fight Before Alleged South Miami Facebook Killing

Facebook messages are shedding light on the final hours before a South Miami man allegedly shot his wife and posted a photo of her body on the social networking site.

In the messages, which were released Tuesday by the Miami-Dade State Attorney's Office, Jennifer Alfonso recounted to a friend how her husband, Derek Medina, was supposed to wake her up to watch a movie the night before the Aug. 8 shooting but had fallen asleep.

"I feel like I'm begging for him to hang out with us.. I already no what his excuse is going to be," Alfonso wrote to friend Kelly Barry.

"Its stupid sh-- like this that makes me think crazy sh-- you no.. like it doesn't do anything now but later on it will eat away at my brain," she wrote later.

Alfonso later told Barry that Medina came in the room and left without saying anything.

"We fought," she wrote. "He doesn't give a sh--. He called me a b--ch LOL."

"He said I was inconsiderate," she wrote, before ending the exchange, saying "I feel like I want to leave."

A short time later, police said Medina, 31, shot Alfonso, 26, inside their home after a fight. According to a police search warrant, Alfonso grabbed a knife, but her husband took it away from her and put it back into a kitchen drawer. Medina also told police that Alfonso punched him.

According to the warrant, Medina admitted to posting the photo and an admission on his Facebook page before he surrendered to police.

"Im going to prison or death sentence for killing my wife love you guys miss you guys take care Facebook people you will see me in the news," he wrote. "My wife was punching me and I am not going to stand anymore with the abuse so I did what I did I hope u understand me."

Alfonso's 10-year-old daughter was home during the alleged murder but wasn't harmed, officials said.

Medina has been charged with second-degree murder, shooting a deadly missile and child neglect without great bodily harm. He has pleaded not guilty to the murder and child neglect charges but didn't enter a plea for the shooting a deadly missile charge. His trial date is scheduled for Nov. 4.
