MIAMI (AP) — Three South Florida attorneys will represent a man accused of killing his wife and then posting pictures of her body on Facebook.

A judge on Friday approved a request for preservation of evidence in the case against 31-year-old Derek Medina. The attorneys took over from the Public Defender's Office, which initially represented Medina.

Authorities say Medina posted a Facebook status on Aug. 8 in which he confessed to killing 26-year-old Jennifer Alfonso. Moments later, a gruesome photo appeared on the page of a woman slumped on the floor. Medina later told police he had gotten into an argument with Alfonso that day.

The Miami Herald reports Medina sat silently in court, wearing a red jumpsuit and shackles around his wrists and ankles.

An arraignment is scheduled for Aug. 29.
