Article with the Best Introduction
It was December 12, 1978. Just as every morning, Chief Detective Joseph Kozenczak sat in his office on the first floor and went over the reports from the past 24 hours. Sipping some coffee, he started off by reading through Monday’s list of events: “a domestic argument which ended with the police restoring peace, a break-in on Phoenix Drive, a report of an abandoned vehicle, several malfunctioning alarms in businesses requiring police assistance to restore, etc.”1 It wasn’t until midway through the list of Monday’s Report when Joseph Kozenczak came across the name Robert Jerome Piest, a missing persons report filed by his mother Elizabeth Piest.2
Joseph Kozenczak had found this to be very interesting because of the narrative part of the report. As described from the report, the mother and son had a very repetitive routine. Elizabeth would pick up her son at 5:30 p.m. after his gymnastics session at Maine West High School in Des Plaines, Illinois. Then she would have his dinner and milk to eat in the car, and he’d usually eat it as Elizabeth drove to Nisson Pharmacy, where Robert worked. But Monday was a bit different. Rob ate a sandwich. Elizabeth had saved her birthday cake to be cut after picking up Rob from work. She arrived at Nisson Pharmacy at 9 p.m., and she went in to get Rob. Rob asked his mother to wait outside so he could discuss a summer job with a construction contractor. Twenty minutes passed and Elizabeth went to check the parking lot only to find that she was alone. There was no sign of Rob, or this mysterious construction contractor. Not knowing who the contractor was, Elizabeth called her son’s friends and one of the owners of the pharmacy, and found out that his name was John Wayne Gacy, Jr.3
Something about the report didn’t seem right to Detective Kozenczak. He knew Robert had no reason to leave his family, or run away from home, so where was he? He read the report one more time. While reading through the report, Detective Kozenczak found that the young boy Robert was born the same year as his own son, as well as the fact that the two boys attended the same high school (Maine West High School).
Detective Kozenczak decided to put “Ronnie” Ron Adams to investigate the Piest missing persons case. He chose Adams because he wasn’t just a good cop, but he also had passion for his job. He knew Adams was the right one for this case. Also Kozenczak knew about the fact that Adams had a family, and had hoped it would make things more personal while continuing the harsh investigation. Adams didn’t waste any time at all. He talked with the two brothers who owned the pharmacy, and found out that the contractor, John Gacy, had been in the store not once, but twice. To check Gacy’s alibi, Adams then called Gacy at 9:15 a.m. and Gacy explained that he had been present at the pharmacy, but only because of some remodeling plans, and to gather or see if there were any tools he needed. He also said, “He had not spoken, nor had any personal contact with the missing boy.” It was at this point that things started to not add up in the mind of Detective Kozenczak.4
The investigation “wasn’t getting anywhere fast” as Kozenczak put it. It was not until Detective Jim Pickell stepped out of his office, when things started to take off. The two detectives knew about Gacy’s arrest, but did not know exactly what John Wayne Gacy had been arrested for. Pickell went off in search of what Gacy had been arrested for. Pickell was known to get what he wanted, and always did what he had to in order to obtain it.
The two Detectives then read Gacy’s rap sheet, which was filled with numerous crimes, the first and most important: “20 May 1968-Waterloo, Iowa-Sodomy-10 years.” The word “sodomy” stuck into the two detectives’ heads. After going through the rap sheet, the two detectives were both convinced Gacy was deeply involved in the disappearance of Robert Piest.5 Later that day,Detectives Kozenczak, Pickell, Olsen, and Sommerschield went to Gacy’s house to interview him. Kozenczak and Pickell went inside, while Sommerschield and Olsen waited outside on the street. While inside the house, Gacy sat in his recliner, and not much happened except for the same story he gave Adams over the phone. Kozenczak had coaxed Gacy into coming down to the station, and after a few attempts, it finally worked.
Gacy called and came in around noon. He had no problem telling the same story, as well as filling out the witness report; but he did seem agitated after he refused a lie detector test. While that was going on, Kozenczak was gathering his warrant, and on his way back to get Gacy’s keys. At 5 p.m. Kozenczak rushed in to find Gacy and asked for his keys. Gacy was terrified and filled with anger. He fought and argued before he was forced to give up his keys.
As Kozenczak put it, “I put the key in the door and I felt like I was stepping into the unknown.”6 They searched the house and found a crawl space that was creepy, but nothing seriously incriminating; but they did take many things as evidence. They took clothes, papers, towels, shoes, etc. It was not until the third warrant was issued that Detective Kozenczak decided to crawl into the crawl space. That’s when everything changed in the blink of an eye.
When Detective Kozenczak crawled into the muddy crawl space, he was face to face with not one or two, but three bodies. He encountered the three bodies in the first ten minutes he had spent in the crawl space. A call was made, and as soon as the news was told to Gacy about the findings, he admitted to the murders with no hesitation. Once the crime scene was investigated and dug up, and everything was done, the Medical Examiner was called in, and over the course of a few weeks or so, twenty-four more bodies were discovered in the ground beneath Gacy’s crawl space. As reported by Detective Kozenczak, “There was plastic over their heads and most of them were partially clothed. They had been strangled and were in various stages of decomposition. There were skeletons everywhere.”7 But that wasn’t the end of finding bodies. The serial killer admitted that there was not enough room left for his last six victims. With no room left for the bodies, Gacy had turned to the river, dumping his last victim Robert Piest into the Des Plaines river. The river was near the Chicago Airport. Gacy admited to dumping the body in the winter of 1978, although they found his body in late spring of 1979. Robert’s body had froze, and was conserved in ice until it thawed out late spring.
Justice was finally served when Gacy was arrested and found guilty after a long and devastating trial in March 13, 1980. He received multiple sentences. “The jury quickly returned a verdict of guilty on thirty-three counts of murder, twelve carrying a death sentence, and two charges of sexual assault.” The jury did the right thing by putting a heartless monster like Gacy away. Gacy was executed by lethal injection on May 10, 1994, in the Stateville Correctional Center in Joliet, Illinois. Gacy was pronounced dead at 12:58 a.m.8
The ending somehow did not seem to lift the weight off the shoulders of Detective Joseph R. Kozenczak, as he stated “I thought that I would feel that it was all resolved then. But it wasn’t. It was just hard to live with.”9 Someone will never understand what it was like to be in the chase, but we know how hard and personal it was for Detective Joseph R. Kozenczak. After the chase was done and finally put to rest, Kozenczak retired and went on to write his own book, A Chicago Killer, which was a great insight into what the Gacy Case was like. Unfortunately Joseph R. Kozenczak passed away Wednesday May 13, 2015. He had served on the Des Plaines Police team as Chief Detective for 27 years.10 Detective Joseph R. Kozenczak’s passion, strength, and patience will live on longer than we can imagine. He brought justice to 33+ families and their relatives.

The whole case definitely had to have traumatized Kozenczak, even after catching Gacy, he would still have to cope with these events. It is amazing how Gacy was able to get away with killing around 30 people before getting caught. Furthermore, I wonder what Gacy’s motives were in committing these murders? Were all of his attacks premeditated or done at random? Nicely done and well written article!
Osman Rodriguez
In all honesty, great article! I was hooked from the start and was deeply invested in this article. Very good use of information and just well written. The topic was great! I didn’t know about Gacy whatsoever. This article gives a substantial amount of information and is clear. It is crazy to here of a case like this. You really don’t know what people are like. Gacy, was just cynical, I’m glad everything was eventually resolved.
Justin Garcia
This was a very interesting article. It is sicking however that people like Gacy could be capable of such horrible acts. His number of victims being around 30 is sicking because it shows he had no remorse for taking human life. Overall the article was very well written and told a very well structured narrative. Great article.
Mark Martinez
An extremely well written and put together article. I really liked how at the beginning you start with an introduction instead of the actual story, it is a nice set up for the readers to be pulled into the story. I just can’t imagine the mind set to kill someone let alone over 30 people. It just reminds me how the world can be a crazy place sometimes

I cannot believe I had never heard of Gacy before this. This was such a horrible case. It’s crazy to think that they discovered that he murdered as many as 33 people when they had inclination of it at all and were just expecting to find Robert Piest. Gacy probably did partially inspire Stephen King when he was creating “It”, but he also reminded me of the murderer in the Lovely Bones in the sense that he was luring kids, had a crawl space where he hid them, and had killed so many people without anyone connecting the dots. This was a great article!

This was a very shocking article. I really enjoyed the introduction it was almost like the opening of a show. I am a big fan on crime shows such as Criminal Minds and Law and Order SVU and I believe one of the Law and Order episodes were based off of this story. It is so crazy how it took them three search warrants before they finally decided to look into the crawl space. I wonder why Gacy was so quick to admit to all of the murders after the bodies were found instead of admitting to only the bodies that they had found. I find it a little frustrating that his trial and conviction took so long despite having all of the evidence and even a confession. Although it took so long I’m glad justice was given for the victims.

Having watched countless documentaries, I had no idea that one of John Wayne Gacy’s first victims was in some way associated with the son of the detective of the case. It was so sad to read that a detective came across multiple bodies after looking through a crawl space located on john’s property. Overall it was a sad article to read and also insightful on the infamous murderer.
Tara Sellers
This article was very well written. I wonder why they did not go into the craw space the first time. I can’t believe that many people were murdered without anyone ever finding a patter. The only reason why they caught him was because the chief detective the chief felt something was off about Robert Piest’s missing person’s report. I don’t understand how the pictures of John Wane Gacy as a clown are relevant to the story since what connected him was the fact that Robert talked to him about a construction job.
Alexandria Martinez
A very interesting article, in the past I had heard various things about John Wayne Gacy, however, not too much. It was a good mix of information about Gacy and information about the cops and investigation that went on. This article gave some more insight into what Gacy did and how he ended up being caught. It is fortunate that someone looked into the missing person’s report because it led to the capture of a serial killer.
Sarah Mares
Personally, I love reading or watching anything related to crime, the stories of serial killers, unravelling mysteries, etc. so this article immediately caught my attention just with the title alone. I really enjoyed reading this article because of how captivating the story of John Wayne Gacy was told. There are no greatly explained reasons as to why people do such messed up things and commit such horrible crimes, but unfortunately, there are those out there who feel murder and crimes are necessary to their lives, despite what the consequences might be. I found this article to have very intriguing content on John Wayne Gacy’s life and the crimes he commited. Great article!
