Underneath, Facebook friends left aghast comments. "That is my friend there," one wrote. Another wondered, "What happened?"

Officers came to Medina's South Miami home to find the dead body of his wife Jennifer, 26, as well as the couple's 10-year-old daughter, who was unharmed.

Medina told police that he and his wife got in a heated argument when she began to punch him. He claimed he went upstairs to get a gun and when he came back she was holding a knife. Then, he said, he disarmed her, put the knife away, and shot her.

Medina is being charged with first-degree murder.

The gruesome photo was up on his Facebook page for more than five hours before the company took his page down. A Facebook spokesperson issued the following statement to the AP:

The couple originally married in January 2010, got divorced two years later, then remarried three months after that.

Medina, oddly enough, was prolific writer of self-help e-books. His latest was titled, How I Saved Someone's Life and Marriage and Family Problems Thru Communication.
