SOUTH MIAMI, FLORIDA (PIX11) – This was taking Facebook posting way too far, and the “status” was murder.

31-year-old Derek Medina of South Miami made a confession on his “wall” Thursday, not long after fatally shooting his wife in the head at their townhouse.

He also posted a photo of his 26-year-old spouse, lying on her back with blood splattered on her face. Under the picture, he wrote, “Rip Jennifer Alfonso.”

“Friends” who checked out Medina’s wall Thursday were stunned to see his remarks about the murder.  “I’m going to prison or death sentence for killing my wife,” the status report began.  Then, addressing his friends, he wrote, “Love you guys miss you guys take care Facebook people you will see me in the news.”  It was only at the end of his “status” that Medina gave a reason for killing his spouse.  “My wife was punching me and I am not going to stand anymore with the abuse so I did what I did and I hope you understand me.”

Medina later turned himself in to police, and the couple’s ten-year-old daughter was found in the townhouse unharmed, her mother’s body in the kitchen.


A friend of Jennifer Alfonso’s said the young mom had tried to make the marriage work.  The couple had originally married in 2010, only to get divorced two years later. Three months after the divorce, they remarried.

When the suspect’s father, Derek Medina, Sr., was asked about the killing, his voice shook, as he replied, “Only God knows the reason. Only God knows.”

Ironically, Medina, Jr. was a “self-help” writer who had produced books about keeping marriages together and lines of communication open.

Medina told police that after punching him, his wife came at him with a knife.  But Alfonso’s friend, Daysi Fernandez, didn’t buy that story.

The murder case was making national news, as PIX11 looked at previous, criminal cases in New York where Facebook was a factor in solving the crime.

In May 2012, PIX11 reported the story of the Brower Street gang, who were breaking into houses in Crown Heights, Brooklyn to steal electronics and then bragged about it on Facebook.

At the time, police officer Michael Rodriguez explained to PIX11 how he “friended” some of the alleged gang members on Facebook and learned where their next “job” would be.

Police ended up recording the break-ins on undercover footage and busted 14 alleged members of the gang. During one break-in, four men were accused of sexually assaulting a woman, as she was tied up inside her home.

Derek Medina now faces the prospect of life in prison, if he’s convicted of killing his wife.
