The Staten Island EMT who was fired last month for posting on his Facebook a crime scene photo of murder victim taken on his cell phone has now been arrested and charged with official misconduct. Former NYPD Detective Mark Musarella, who had been involved in high-profile rescues while on the force, took a photograph of Caroline Wimmer after she had been strangled with a hair dryer cord in a West Brighton incident sparked by a rumor started on MySpace. Musarella's lawyer says his client, described as having a "raw sense of humor," will plead not guilty and that the photo was posted by accident. The Staten Island DA told reporters that Musarella "ignored his training and professional ethics and acted in a cruel and callous manner." He could face up to a year in prison if convicted.
