John Wayne Gacy's house location.

This is the location where John Wayne Gacy's house once stood.

It is situated at 8215 West Summerdale Avenue in Chicago, Illinois.

The original house was demolished by a wrecking crew on April 11th, 1979. The decision to level Gacy's home came after police excavations at the property made it structurally unsound.

Although the building itself no longer exists, it is still eerie to think that 29 men were brutally murdered and then buried on this lot.

Between 1972 and 1978, Gacy killed at least 33 victims. Many of them were teenagers and young men.

His youngest confirmed victims were Samuel Dodd Stapleton and Michael Marino—both of whom were only 14 years old.

John Wayne Gacy's M.O. involved luring victims back to his home and then plying them with alcohol. Once they were at ease, he would trick them into putting on a pair of handcuffs.

As soon as the handcuffs were secured, Gacy would begin to carry out sadistic acts of rape and torture. He also liked to taunt his victims and partially drown them.

Once he had satisfied his sadistic needs, he would then strangle his victim to death using a rope before burying their body in the crawlspace beneath his house.

In 1980, John Wayne Gacy was found guilty of 33 charges of murder and sentenced to death. After spending fourteen years on death row, he was executed by lethal injection on May 10th, 1994.

Why was John Wayne Gacy's house demolished?

John Wayne Gacy's house demolished

The house was not demolished for moral reasons.

The property was deemed to be unsafe after police excavations weakened the structure. At that point, investigators were unable to continue their work unless the building was torn down.

In other words, the police suspected that there might be more victims. However, there were fears that the house might collapse on top of them if they continued digging.

Consequently, representatives from Cook County petitioned the Circuit Court and asked for permission to level the site.

After the structure was demolished, the lot remained empty for a number of years. The current house was built seven years later, in 1986.

Robert Piest.

Gacy approached his final victim at the Nissan Pharmacy in Des Plaines. Nowadays, the building is home to a daycare center called Millie's House.

At the time, Robert Piest (15) was working part-time at the pharmacy.

On December 11, 1978, Gacy visited the pharmacy to discuss a remodeling job with the owner. After he spotted Robert, he mentioned that his construction firm paid teenage boys $5 per hour.

Back in 1978, $5 per hour was very substantial for a teenage boy.

Later that day, Robert's mother arrived to pick him up. However, he told her to wait a little while because he needed to talk to a contractor about a potential job.

However, Robert never returned that evening. Within an hour of leaving the pharmacy, Robert was murdered at Gacy's house on Summerdale Avenue.

It was the disappearance of Robert Piest that ultimately led to Gacy's arrest.

Gacy murdered at least 33 teenagers and young men between 1972 and 1978. Their ages ranged between 14 and 21.

Although he committed his first murder in 1972, it wasn't until April of 1976 that his killings became a regular occurrence. That was roughly one month after his divorce from his second wife Carole Hoff was finalized.
