Piermont, New York (CNN) -- Autopsy results were released on Monday for a bride-to-be and best man who were killed in a boating accident last weekend on the Hudson River. Lindsey Stewart died "as a result of drowning and severe head injuries" and Mark Lennon died "as a result of drowning" and "suffered only minor bodily injuries," according to a press release from the Rockland County Medical Examiner's office. Lennon and Stewart disappeared late Friday when a 21-foot Stingray power boat they were passengers on slammed into one of three construction barges strapped together near the Tappan Zee Bridge, 25 miles north of Manhattan. Lennon was to be the best man in Stewart's wedding to Brian Bond on August 10.
