No charges against Medina have been announced. Police found Alfonso's body in a townhouse. A 10-year-old girl was also at the scene. Police did not reveal how she is connected with the couple, the Miami New Times reported. She was escorted out of the home by police. Investigators have not yet confirmed his crimes were on social media, but a screenshot taken before Facebook removed his page entirely shows that he suggests to friends that he would be on the news for killing his wife.

"I'm going to prison or death sentence for killing my wife. Love you guys. Miss you guys. Take care. Facebook people you'll see me in the news. 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," Medina's post read.

He followed up by posting a picture of a woman's body. She was lying on her back, knees bent with her head leaning on kitchen cabinets. Her face and left arm were bloody. He captioned the photo "Rip Jennifer Alfonso." One commentor said "That's my friend there" and tagged Alfonso. The couple had been married since April 2012, and Alfonso had just changed her profile picture to a photo of she and Medina kissing the night before she was killed, the Daily Mail reported. The two also uploaded a picture of themselves and a young girl dining at a restaurant, which appeared to be taken around 24 hours prior.

Medina is a self-published author, writing e-books with titles such as "How I Saved Someone's Life And Marriage And Family Problems Thru Communication" and "World Just Ask Yourself Why We Are Living a Life Full of Lies and How I an Emotional Writer Made All of My Professional Dreams Come True Blocking Society's Teachings." South Miami police has completely turned over the case to Miami-Dade police.
