"Thomas had a physically large mouth full of crooked teeth and piggish eyes that were too close together. This suggests that Thomas suffered from Fetal alcohol syndrome which is a disorder or permanent birth defects that occur in women when they consume alcohol during pregnancy. The alcohol can also damage neurons and brain structures, and cause physical, mental and behavioral problems. which is caused from the narrowing of the palpebral fissures. It also creates an array of primary cognitive and functional disabilities including impulsive behavior, attention defecits and poor cause-effect reasoning which Thomas displayed signs of. One of the physical telltale signs of fetal alcohol syndrome is that the eyes may seem visually too close together. Federal Bureau of Investigation (FBI) agent Joseph O'Brien would state that Thomas was unfortunate to not "escape the telltale signs of inbreeding- the piggish eyes, the sloping brow, the blotched skin that went with hypertension that made Thomas and other mobsters into caricatures of thuggishness".

Fetal Alcohol Syndrome would explain a few of the the stories about him.

"With his first wife Catherine he fathered a severely autistic son and namesake, Thomas C. Bilotti born on March 30, 1974 who was institutionalized when he reached the age of a toddler. Thomas was said to have loved his son dearly and visited him regularly, though he never spoke of him publicly. His son and namesake Thomas C. Bilotti passed away on September 16, 2003 in Port Jefferson, New York at the age of twenty-nine".

I found that quite sad. Everything about that article was pretty sad actually. A depressing read.
