Investigators are still trying to piece together the sequence of events that led to an attack on a Florida couple in which a 19-year-old college student is accused of killing them and biting the man's face. But Martin County Sheriff's Lt. Michael Dougherty tells the TC Palm (http://bit.ly/2b3AAkH ) neighbor Jeff Fisher came to their aid after hearing the screams of 53-year-old Michelle Mishcon. Fisher told deputies Mishcon and her 59-year-old husband John Stevens III were still alive when he got there Monday night. But Dougherty says they were dead by the time deputies arrived and found Austin Harrouff on top of Stevens, biting his face. Sheriff's spokeswoman Trisha Kukuvka says he's conscious but heavily sedated.
