Kenneth Alessio Bianchi was born on May 22, 1951, in Rochester, New York, to an alcoholic prostitute who gave him up for adoption two weeks after he was born. He was adopted in August 1951 by Nicholas Bianchi and his wife Frances Scioliono-Bianchi, and was their only child.
Bianchi was deeply troubled from a young age, with his adoptive mother describing him as “a compulsive liar” from the time he could talk. He would often fall into inattentive, trance-like daydreams where his eyes would roll back into his head. Based on these symptoms, a physician diagnosed the five-year-old Bianchi with petit mal seizures. Bianchi was also frequently given physical examinations by doctors because of an involuntary urination problem, causing him a great deal of humiliation.
