Day on 1944 in Chicago. Gacy had 2 siblings, an older sister and a younger sister.
John was not a popular kid in school, but was liked by his friends and neighbors.
He participated in boy scout and other activity like any other normal boys his age.
John had a head injury from a swing on the swing set.
It caused blood clot in the brain, and many blackouts between age 11-16.
Gacy's father was an aocoholic who physically abused his mother and verbally assaulted him and his sisters.
Due to many traumas that John went through during his teenage years, he was not able to graduate high school.
After dropping out, John left his home and started working Las Vegas, but the plan did not last and soon he returned to Chicago.
