Derek Medina, the Florida man who posted a photo of his dead wife\'s body on Facebook, was denied bail after a lengthy hearing in Miami. Prosecutors described the killing of Jennifer Alonso, 27, as an \"execution,\" during Tuesday\'s hearing, The Miami Herald reported. Defense lawyers said Medina is a victim of spousal abuse. \"Battered spouse syndrome -- it doesn\'t only apply to women,\" lawyer Saam Zangeneh said. Medina, 31, has admitted shooting Alonso in their South Miami home in August and posting a picture of her corpse on Facebook. But he said in a statement to police that he acted in self-defense, that his wife \"kept on punching me like crazy.\" Prosecutors and investigators say the evidence shows Alonso was in a defensive position when she was killed, on her knees and covering her face. \"The victim appeared to be in a cowering position,\" Miami-Dade Detective Jonathan Grossman testified at Tuesday\'s hearing. Grossman also said Medina told Alonso\'s former boyfriend he would kill his wife if she ever tried to leave him.
