A Miami man who used his Facebook page to post a photograph of what he said was his wife's dead body, along with a statement that he had killed her, shot his wife after police said she began punching him.
Derek Medina, 31, was charged with first-degree murder late Thursday after he spent the evening revealing to police details of what led him to allegedly fire multiple rounds into his wife, Jennifer Alfonso, 26, according to an arrest affidavit released today.
He has not entered a plea and a lawyer has not been named.
The couple had a verbal dispute around 10 a.m. Thursday, at which point police said Medina told them he pointed his firearm at Alfonso. She then walked away from the argument, the affidavit said, and returned a few minutes later to tell Medina she was leaving him.
Medina said he followed his wife into the kitchen to confront her, at which point she began punching him, according to the affidavit. Police said Medina told them he then went upstairs, grabbed his gun once again, and held it in his right hand as he walked downstairs toward Alfonso, who responded by grabbing a knife.
