New questions about the autopsy of Marlon Brown. He is the Florida man struck and killed by a police car. The medical examiner ruled his death an accident, and the officer behind the wheel is not facing any criminal charges. But Brown's family is calling it an execution and demanding justice. The medical examiner at the center of the case may be familiar to those who followed the George Zimmerman Trial. 360's Randi Kaye has the latest.
