Derek Medina, 31, also wrote a message appearing to confess to murdering wife Jennifer Alfonso, 26, before handing himself into police.
The graphic image shows a blood-soaked woman slumped on the floor with the macabre caption “RIP Jennifer Alfonso”.
Shortly before the photograph was uploaded, Medina updated his status saying: “I’m 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.
“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.” (sic)
Medina is now being quizzed by detectives in Miami after turning himself in on Thursday morning, hours after the shooting.
Police then discovered Ms Alfonso’s body at the couple’s home at 5555 SW 67th Avenue.
Medina’s 10-year-old daughter was also found unharmed at the property and was seen being led away by officers wrapped in a red blanket.
