The Medical Examiner for Romeyn County during the 1950s, 1960s, and 1970s, Dr. Giunta presided over the strange autopsy of Supersonic in 1966.
Supersonic had suffered tremendous trauma and blood loss, due to a battle with Lady Lethal and by all medical knowledge available at that time, he was totally and completely certifiable as dead. However, as Dr. Giunta prepared to make his first incision, Supersonic got up off the autopsy table...
Fast forward eight years to a court room in downtown Astro City where defense attorney Vince Oleck used this resurrection as one of many super-heroic incidents to establish a basis of reasonable doubt in a murder trial. The victim in that trial had been autopsied and pronounced dead by the same coroner, Dr. Guunta who examined Supersonic. The coroner's mistake in 1966 was used by defense attorney Oleck, to plant doubt about the autopsy results in 1974. Vince argued that given the nature of the times, one couldn't be 100% sure the victim was truly dead. ("Knock Wood")
Dr. Giunta is a likely reference to artist John Giunta.
