Though not reported contemporaneously, research (most notably by authors Harrison and Swicegood) has revealed evidence of Tanzler's necrophilia with Elena's corpse. Two physicians (Dr. DePoo and Dr. Foraker) who attended the 1940 autopsy of Elena's remains recalled in 1972 that a vaginal tube had been inserted in the vaginal area of the corpse that allowed for intercourse. Others contend that since no evidence of necrophilia was presented at the 1940 preliminary hearing, and because the physicians' "proof" surfaced in 1972, over 30 years after the case had been dismissed, the necrophilia allegation is questionable. While no existing contemporary photographs of the autopsy or photographs taken at the public display show a tube, the necrophilia claim was repeated by the HBO "Autopsy" program in 1999.
