The Office of the Chief Medical Examiner said a human skull found in Wilmington has been positively identified as Gary R. Mayo of Wilmington, who has been missing since Thanksgiving Day 2007.


The Office of the Chief Medical Examiner says the human skull found Jan. 4, 2011, in Wilmington has been positively identified as Gary R. Mayo, born April 29, 1963, of Wilmington.

Mayo reportedly fell off a 20' boat into the Christina River on Thanksgiving Day, November 22, 2007. There were several unsuccessful attempts to rescue him before he submerged into the river and extensive searches were unsuccessful.  The investigation was conducted by Delaware State Police.
 
On Jan. 4, 2011, human remains were exposed on muddy tidal flats and recovered by a boater along the shoreline of the Delaware River about 300 yards south of the Port of Wilmington. An investigation was conducted by the Wilmington Department of Police, Delaware Office of the Chief Medical Examiner and Delaware State Police.

The nearly complete male cranium (lacking a lower jawbone) was in very good condition despite undergoing some erosion due to water movement, such as tides, waves, currents. Remains were examined by the Delaware Office of the Chief Medical Examiner staff, Forensic Odontologist Dr. Richard Scanlon of Lewiston, Pa.; Forensic Radiologist Dr. Gil Brogdon of Mobile, Ala.; and Forensic Anthropologist Dr. Marcella H. Sorg of Oreno, Maine.  
 
Based on macroscopic and osteometric anthropological assessment, radiological comparison to CT scans (anti-mortem CT scans provided by Papastavros Associates Medical Imaging and Forensic dentistry, anti-mortem dental records provided courtesy of Dr. Richard Jacobs DDS, of Claymont), positive identification was established as Mayo.
