Dr. DiMaio was born in Brooklyn New York on March 22, 1941 to Dr. Dominick DiMaio and Violet DiMaio. He graduated from New York’s Downstate Medical School in 1965 after which he proudly served as a Major in the Army as the Chief of the Legal Medicine Section and the Chief of the Wound Ballistic Section at the Armed Forces Institute of Pathology in Washington D.C. After his military service, he served as a Medical Examiner in Dallas, Texas, from July 1972 to February 1981. He then moved to San Antonio to become the Chief Medical Examiner of Bexar County, a position he held for 25 years before retiring in December 2006. During this time, Dr. DiMaio was also a Professor at the University of Texas Health Science Center San Antonio Medical School and served as the Editor-in-Chief of the American Journal of Forensic Medicine and Pathology for 27 years, from 1991 to 2017. After his retirement, he was appointed by Governor Perry to the Texas Forensic Science Commission and by President Obama to the National Commission on Forensic Science.
Dr. DiMaio was a world-renowned forensic pathologist and expert on gunshot wounds. He was the author to a number of textbooks including Gunshot Wounds, DiMaio’s Forensic Pathology, Excited Delirium, and Handbook of Forensic Pathology as well as the autobiography Morgue: A Life in Death. His expertise was sought in numerous high-profile cases including the assignation of John F Kennedy, the exhumation of Lee Harvey Oswald, Genene Jones, Phil Specter, Michael Morton, Ruby Ridge, Claus Van Bulow, Bob Crane, George Zimmerman, the West Memphis Three, the Smolensk airplane bombing, and many many others. He was also invited to share his knowledge and experiences in educational lectures all over the United States and internationally, including England, Spain, Argentina, Israel, Honduras, and Italy. However, despite all of these accomplishments, he was most honored and proud when the Bexar County Forensic Science Center was named after him in 2018.
Although he was born and raised in New York, he loved San Antonio and being a Texan. He was a voracious reader, loved history, adored his dog, Sugar, and would never turn down chocolate or a Coca-Cola. Most importantly, he was a devoted father and husband, who was honest and generous to a fault. He is survived by his loving wife of 50 years, Theresa DiMaio; his daughter Samantha DiMaio, son Dr. Dominick DiMaio; grandchildren Vincent, Giovanni and Gemma DiMaio; his sister Dr. Ann DiMaio and her husband Dr. Bill DiMaio; and his cousins, Dr. Pascale deCaprairis and Angela Salerno.
