Lombroso was particularly taken by many striking personality characteristics that Villella possessed; agility and cynicism being some of them. Villella’s alleged crimes are disputed and Lombroso’s research is seen by many as northern Italian racism toward southern Italians. Upon Villella's death, Lombroso "conducted a post-mortem and discovered that his subject had an indentation at the back of his skull, which resembled that found in apes". He later referred to this anomaly as the "median occipital depression". Lombroso used the term "atavism" to describe these primitive, ape-like behaviors that he found in many of those whom he deemed prone to criminality. As he continued analyzing the data he gathered from Villella's autopsy and compared and contrasted those results with previous cases, he inferred that certain physical characteristics allowed for some individuals to have a greater "propensity to offend and were also savage throwbacks to early man". These sorts of examinations yielded far-reaching consequences for various scientific and medical communities at the time, and he wrote, "the natural genesis of crime implied that the criminal personality should be regarded as a particular form of psychiatric disease"., which is an idea still seen today in psychiatry’s diagnostic manual, the DSM-5, in its description of antisocial personality disorder. Furthermore, these ideas promoted the concept that when a crime is committed, it is no longer seen as "free will" but instead a result of one's genetic pre-disposition to savagery. Lombroso had numerous case studies to corroborate many of his findings due to the fact that he was the head of an insane asylum at Pesaro. He was easily able to study people from various walks of life and was thus able to further define criminal types. Because his theories primarily focused on anatomy and anthropological information, the idea of degeneracy being a source of atavism was not explored till later on in his criminological theory endeavors. These "new and improved" theories led to the notion "that the born criminal had pathological symptoms in common with the moral imbecile and the epileptic, and this led him
