Facebook continues to shed light on a murder that made headlines when the perpetrator posted photos of his wife's body and a confession on his public profile page.

NBC 6 has obtained messages that Jennifer Alfonso, the wife and victim of Derek Medina, sent to a friend just hours before her death August 8 that show the couple had been fighting.

From NBC 6:

"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."

Just hours later, Medina shot Alfonso in their South Miami townhouse before posting his confession on Facebook and turning himself into police.

NBC 6 also obtained a journal allegedly belonging to Alfonso titled "Inside the Mind of an Insane Woman." In it, Alfonso wrote things like being so jealous of her husband for checking out other women that she wanted to murder him, and not being able to sleep because she was thinking about zombies and the end of the world.

The two had a rocky, on-and-off relationship but enjoyed exploring the supernatural together and had gone on ghost tours.

Did Derek Medina Believe He Was the Next George Zimmerman?

Derek  also reportedly wanted to be a neighborhood watchman. 

 Derek is an avid enthusiast of mixed martial arts. He is seen in YouTube videos hitting punching bags. He also has multiple photos of himself holding guns and knives on his Facebook page.

A few of Jennifer’s former co-workers are speaking out and claiming that Jennifer had been the victim of a very abusive marriage.

“She would be bruised up,” Amanda Cooper said.

Another co-worker, Cathy LaBella, said: “He would always come back, begging her. She would say he was going to change. She was in love with him.”
