Following the fatal shooting, Medina took to his Facebook to post a photo of his dead wife with a caption that said, "RIP Jennifer Alfonso."
The graphic photo showed Alfonso bent backwards on the floor with her knees bent, her left arm and face covered with blood.
After posting the photo, Medina later wrote the following on his Facebook:
"I'm 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 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"
According to police reports, following his Facebook confession, Medina changed his clothes and left the scene without calling 911. He then went to family members, telling them what he had done, before turning himself in to police.
