On January 15, 2019, a plumber named Jamal Washington pulled his work van into the parking lot of Lincoln Heights Middle School in Milwaukee, Wisconsin. It was his third visit that month, always for the same problem: clogged drainage in the basement bathrooms. He was 34 years old, a single father of two, and had worked for Donovan Plumbing Services for six years. His boss, Frank Donovan, had made his instructions clear that morning: snake the drain, don’t overthink it, get in and out.
Donovan had owned the company for 30 years, and he knew that temporary fixes meant recurring calls and steady revenue. Jamal understood the business logic. He just didn’t agree. His father had been a plumber too, and he had taught Jamal a different rule: do the job right or don’t do it at all.
So when Jamal fed his camera snake into the drain and saw something that looked like fabric deep in the pipe, he did not push it through and move on. He studied the image. It looked like a backpack strap. It looked like clothing.
He decided he needed access to the main drainage cleanout, which was located in a sealed-off boiler room that the school had marked as structurally unsafe and kept behind chains and a padlock. The janitor, Jerome Caldwell, a 52-year-old Vietnam veteran who had worked at the school for 28 years, unlocked the door reluctantly. The room inside was not damaged at all. The walls were solid, the ceiling intact, the floor level.
The room had been sealed for reasons that had nothing to do with structural issues. Jamal found the large cast-iron access panel in the far corner and began removing its eight rusted bolts. As the last one came free, he lifted the heavy cover and shone his flashlight into the opening. What he saw would haunt him for the rest of his life: the bodies of children, wrapped in plastic, stuffed into the drainage system.
Jamal stumbled backward, dropped his flashlight, and collapsed against the wall. He called 911 with shaking hands. He told the operator there were dead children in the pipes, multiple bodies, possibly six or more. Police arrived within minutes.
By the end of the night, the full extent of the discovery was clear. Six juvenile bodies had been extracted from the cleanout, ranging in age from approximately 12 to 16. They were all in various states of decomposition; the oldest had been there for about 16 years, the newest for about four. Someone had treated the bodies with chemicals to slow decay and mask the smell.
All of them still had identification. Homicide detective Sarah Jonas led the investigation. By morning, she had the names: Aaliyah Davis, 14, missing since May 2003; Tyrone Mitchell, 15, missing since September 2005; Kesha Williams, 13, missing since March 2007; Darnell Thompson, 16, missing since November 2009; Jasmine Rodriguez, 12, missing since April 2014; and Kareem Jackson, 14, missing since October 2018. All six were students at Lincoln Heights.
All six were high achievers involved in school activities. All six had disappeared from the school grounds after practices, rehearsals, or club meetings. And all six had been dismissed by police as runaways. Detective Jonas saw the pattern immediately.
The missing person reports were minimal, the investigations superficial, the cases closed without resolution. The children were poor and Black, from the north side of Milwaukee, and the system that should have protected them had failed them. The evidence pointed to one suspect: Jerome Caldwell. He had been at the school for all 16 years, had keys to every room, and worked the night shift alone.
An examination of his digital footprint revealed racist online posts complaining about changing demographics and praising the idea that something needed to be done. A search of his home uncovered a hidden basement wall behind which he kept trophies: Aaliyah’s basketball jersey, Tyrone’s debate trophy, Kesha’s choir medal, Darnell’s game ball, Jasmine’s science fair ribbon, and Kareem’s Black Students Matter button. A locked filing cabinet contained his computer. FBI analysts cracked the encryption and found detailed logs of every murder.
Jerome had documented dates, times, and methods. He had stalked each victim, waited for the right moment, lured them to the boiler room under a pretense, and strangled them with an electrical cord. He wrapped them in plastic, carried them to the cleanout, poured in embalming fluid, and sealed the panel. Nobody ever looked there.
Nobody ever entered that room. Jerome was arrested on February 3, 2019, and charged with six counts of first-degree murder. He waived his right to an attorney and confessed willingly. During his interview with Detective Jonas, he explained himself without a trace of remorse.
He said he killed the children because they were the best and the brightest, the ones who were going somewhere. He called them threats and symbols of what he believed was destroying the country. He told Jonas that if the plumber had not gotten curious, he would have killed more. There was a freshman girl on the debate team he had already been watching.
The trial began on November 4, 2019. The prosecution presented the bodies, the trophies, the computer logs, and the confession. The defense argued mental illness and PTSD from Vietnam, but Wisconsin has no death penalty, and the jury deliberated for only four hours. Jerome was found guilty on all six counts.
The judge sentenced him to life in prison without the possibility of parole, six consecutive life sentences, and told him that the children he murdered had accomplished more in their short lives than he ever had in his miserable existence. Jerome showed no reaction. The investigation did not end with the conviction. Detective Jonas examined every failure that had allowed the killings to continue for 16 years.
Principal Robertson, who had never pushed for deeper investigations into the missing students, was asked to resign. The Milwaukee Police Department faced an internal review that found systemic bias in how missing persons cases were handled, with poor minority children receiving far less attention than middle-class white children. The chief of police issued a public apology and promised reforms. Frank Donovan and Danny Kowalski, the plumbing company owner and the nephew who usually handled the school’s calls, were not complicit in the murders, but their negligence had enabled them.
For 16 years, they had only performed temporary fixes, snaking drains and clearing clogs without ever investigating the main line. If they had done their job properly, the bodies would likely have been found years earlier. They were not charged; negligence is not a crime. But public opinion destroyed the company.
Donovan Plumbing collapsed within three months. Jamal Washington became a local hero. He refused to take shortcuts when it mattered most, and his decision exposed the horror. The Milwaukee Waterworks Department offered him a job as lead plumber for the entire school district.
His first mandate was to inspect the drainage systems of all 163 schools, top to bottom, with no temporary fixes and no shortcuts. He accepted and left Donovan Plumbing. In December 2019, Lincoln Heights Middle School was renamed the Remembered Six Academy. A memorial was erected in the front courtyard: six bronze statues, life-sized, each one capturing the victim in a moment of their promise.
Aaliyah Davis, arms raised in a jump shot, with the inscription, She soared. Tyrone Mitchell, holding a gavel, He spoke truth. Kesha Williams, mouth open in song, She sang hope. Darnell Thompson, football in hand, He broke barriers.
Jasmine Rodriguez, looking through a telescope, She reached for stars. Kareem Jackson, fist raised, He fought for justice. At the dedication ceremony, the families gathered and held hands. The new principal spoke of the six stolen students and the legacy they left behind.
The crowd sang Amazing Grace. Families placed flowers at the base of each statue. Afterward, Patricia Davis, Aaliyah’s mother, approached Jamal and took his hands. She thanked him for caring enough to look, for doing his job right, for bringing her baby home.
He told her he wished he had done it sooner. She refused to accept his regret. She told him there were no what-ifs, that he had given them answers and closure and a chance to bury their children, and that was everything. Jamal drove home that night and held his own children tightly.
The six students had deserved better from every system designed to protect them. He thought about his new job, about inspecting school drainage systems and fixing problems properly. It was no longer just about pipes.
It was about safety and protection, about making sure no one else could hide horrors in plain sight.
