US man kills wife, posts picture on Facebook

Police stand near the orange door which is the front door to a townhouse where seemingly a husband reportedly confessed on Facebook to murdering his wife on August 8, 2013 in Miami, Florida. After apparently murdering his wife and then posting a photo of her body, a South Miami man turned himself in to police. 

Miami - A US man was being quizzed by police on Thursday after gunning down his wife and posting a gruesome picture of her dead body on Facebook, authorities said.

Derek Medina, 31, was being questioned by detectives in Miami after turning himself in earlier Thursday following the shooting death of wife Jennifer Alfonso, 26.

In a macabre twist, Medina had apparently posted a picture showing his slain wife's blood-soaked body on Facebook, under the caption "RIP Jennifer Alfonso," before giving himself up.

In a status update posted shortly before the photo was uploaded, Medina wrote: "You will see me in the news."

"Im going to prison or death sentence for killing my wife love you guys miss you guys takecare 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."

Police said Medina drove himself to the South Miami Police Department following the shooting.

"Officers then responded to the listed location where they found the victim deceased from apparent gunshot wounds, as well as the victim's daughter, 10, who was unharmed," a statement said.

"The motive is unknown at this time."

Medina's Facebook page showing the picture of his dead wife was up for several hours before being taken down later Thursday.

Beneath the photo -- which was shared 170 times before the page was closed down -- were comments from people who appeared to be friends with the dead woman.

"That is my friend there, Jennifer Alfonso," one woman wrote.

"What happened?" asked another.

Local media reports quoted Medina's father, Derek Medina Sr, as saying his son had killed his wife after a violent domestic dispute.

"He just said that his wife picked up a knife on him, and they had a big fight, and he shot her," Medina said.
