In a cell at the DuPage County Jail in Wheaton, Illinois, a man named Michael Jones picked up a Styrofoam cup. He wrote five words on the side of it: I’m sorry for 1985. Weeks earlier, when DuPage County detectives had shown him a photograph of a 15-year-old girl, he had said, “As God is my witness, I’ve never seen her before. ” Mathematical certainty had said otherwise: one in one and a half quadrillion.

Prosecutors took the cup. They sealed it in a bag. Flashback 30 years, 1 month, and 28 days. In the afternoon, a 15-year-old named Kristy Wesselman walked to a suburban supermarket to buy a candy bar.

This is a true crime story about how she got home. Not the way her mother had hoped, but home, finally. Back in the mid-1980s, Kristy Wesselman lived in the Valley View subdivision of unincorporated Glen Ellyn, about 30 miles west of Chicago. She was the third of four children.

Her parents, Sandra and Bob Wesselman, had divorced years before. She lived with her mother. Sandy worked, kept the house running, and tried to make Sunday afternoons feel ordinary. Kristy had just finished her freshman year at Glenbard South High School.

She was, by every available measure, exceptional. She played basketball. She played volleyball. She played softball.

She had been elected president of her freshman class. Before the school year ended, her classmates had already elected her president of the sophomore class she would never attend. She often told her mother that she wanted to move to New York City after college. She wanted to study psychology.

She wanted to open her own practice as a child psychologist. She kept a notebook of vocabulary words she came across while reading. She kept a separate notebook for college essay ideas. She wore a pearl ring on her finger that had belonged to her grandmother.

She had a habit of standing very still in the kitchen doorway when she was listening to her mother talk. Reflecting on Christie’s life years later, her principal at Glenbard South, Peter Abruzzo, would say in his exact words: “She’s the kind of young lady that it’s easy to say nice things about. A good, active student. ” Her mother would say something different, also speaking in reflection.

Years later, in a courtroom in Wheaton, Sandy Wesselman would tell a judge that her daughter’s life had been a great book, and that what Christie would have become will forever be an unfinished book. Glen Ellyn in 1985 was the kind of place where front doors stayed unlocked, and children walked themselves to the store. Valley View was a subdivision of split-level homes and quiet cul-de-sacs. There was a dirt path that ran behind the houses, through a stretch of weeds and undergrowth, and connected the neighborhood to the shopping center on Route 53.

Every kid in Valley View used that path. It was a 5-minute walk to the Jewel Supermarket on the corner of Butterfield Road. On Sunday, July 21st, 1985, Sandy and Christie had a plan. They were going to watch old movies together.

Christie wanted something for the afternoon first. She told her mother she would walk down to Jewel and pick up a candy bar and a bottle of soda. It was the kind of errand that took 15 minutes. The afternoon was warm.

The path was open. The neighborhood was full of families on a Sunday. The only red flag in the days before that Sunday was the absence of one. Glen Ellyn had not had a stranger murder of a teenage girl in living memory.

No suspicious vehicle had been reported circling Valley View. No man in a hat or a windbreaker had been seen on the dirt path the week before. There had been no warning. What investigators would not piece together for 30 years was that a problem had already been driving in and out of the area for years before 1985.

A handyman who lived 2 hours south in the college town of Champaign made regular weekend trips back to the Chicago suburbs to visit family near the Illinois–Wisconsin border. The route ran directly past Glen Ellyn. He had been on parole since 1983. He had served less than 7 years of a 10-to-20 year sentence for the abduction and rape of a young woman in Schiller Park.

His name was Michael R. Jones. At that time, nobody in Glen Ellyn had ever heard of him. The Jewel supermarket surveillance camera caught Kristy standing in the checkout line that Sunday afternoon.

She paid for the candy bar and the bottle of soda. She walked out into the parking lot. She turned toward the dirt path home. By 5:00, she had not come back.

By 6:00, Sandy Wesselman had walked the path herself. She had called the neighbors. She had called Kristy’s friends. The errand was supposed to take 15 minutes.

It had been 3 hours. That evening, Sandy called the DuPage County Sheriff’s Office. The dispatcher logged the call. A patrol unit was sent to Valley View.

The deputies took a description: 15, brown hair, a pearl ring on her finger, and a Glenbard South gym shirt. They walked the dirt path with flashlights as the sun went down. They found nothing. A barbecue had been going on in a backyard just off the path that afternoon.

Children playing in a sprinkler, music on a transistor radio. Nobody had heard a sound. At 11:15 in the morning on Monday, July 22nd, 1985, Detective Kevin Buckholtz of the DuPage County Sheriff’s Office walked along the dirt path behind Valley View. He had been on the case since the night before.

Sandy Wesselman had not slept. About 60 yards from the back of the Jewel parking lot, Buckholtz stopped. There was a pile of weeds and leaves at the edge of the path. Something pale was visible inside it.

He moved a branch. Kristy Wesselman was lying in the weeds. She was partially undressed. There were stab wounds to her chest.

A shoelace had been tied tightly around her neck. About 4 feet away, half buried in the dirt where it had fallen, was a candy bar with one bite taken out of it. Beside it lay a glass bottle of soda. The pearl ring her grandmother had given her was gone from her finger.

Buckholtz did not move the body. He called it in. Within an hour, the dirt path was a crime scene. Within two, a coroner had arrived.

By that evening, a small evidence box had been delivered to the DuPage County crime lab. Inside it was a sealed rape kit collected during the autopsy containing biological material that the technician of 1985 had no way to identify fully. At this stage in 1985, there was no national DNA database. The kit was logged, refrigerated, and shelved.

Its significance would only become clear much later. Investigators reconstructed what they believed had happened. Kristy had bought the candy bar and the soda. She had walked out of the Jewel.

She had taken the dirt path toward Valley View. She had opened the candy bar. She had taken one bite. Somewhere between 50 and 60 yards down the path, evidence suggested she was attacked from behind.

There was no sign of a struggle on the path itself. Investigators believed she was dragged into the weeds within seconds. In the broken undergrowth, the examiner counted eight stab wounds, all to the chest. The killer had used a single-edged blade.

The shoelace appeared to have been taken from her own shoe. At some point during or after the assault, the pearl ring was pulled from her finger. It has never been recovered. The attack took place in broad daylight on a Sunday afternoon.

A family was hosting a barbecue in a backyard yards through the brush. Children were playing in a sprinkler. Music was on a transistor radio. Nobody had heard a sound.

Nobody had seen a man enter or leave the path. Investigators believed the killer knew the area. Investigators believed he had used the path before. Investigators believed he was probably gone within 10 minutes of the ambush.

They were right about all three. The story the public would come to know was the headline: a 15-year-old girl was murdered on a suburban path. But years later, the story Sandy Wesselman could not stop telling was different. Christie had been the kind of student who studied while watching television.

The notebooks she kept were the work of a child preparing four years ahead of schedule to apply to college. The spring before she died in 1985, she had told her mother she wanted to apply to NYU. She wanted to study psychology and stay in New York for her clinical work. She wanted children.

She wanted to help children. The night before she died, she had been reading in bed. She had asked her mother to look at one of her sentences. She had been trying to write a personal statement for a college application she was four years too young to send.

Sandy kept the notebook. She kept it for the next thirty years. When detectives interviewed Sandy in the weeks after the murder, she told them about Christie’s vision for the future. They wrote it down.

They closed the file at the end of the night and went back to chasing leads on the dirt path. Sandy went back to a house with three remaining children, a daughter’s notebook on the bedside table, and a question she would carry for the rest of her life. The DuPage County Sheriff’s Office pursued the case the way good investigators pursued cases in 1985. Detective Kevin Buckholtz worked it as the primary.

He had backup from a rotating roster of deputies and detectives. They interviewed every house on the Valley View streets that backed onto the dirt path. They interviewed the cashiers at the Jewel. They reviewed the surveillance tape from the supermarket.

They walked the path in daylight and at dusk to time how long the killer had to act. They pulled hundreds of leads from four states. They tracked motorcycle gangs and drifters. They looked at every registered sex offender within 50 miles.

None of it broke. Within the first weeks, the investigation began to harden around one name. Dana Henry was a local man whose mother lived in a house roughly 100 yards from where Kristy was found. He had been home that Sunday.

He had no alibi that could be independently verified. Buckholtz and other detectives began to focus. They brought Henry in. They asked him to remove his clothing for examination.

They held him in the DuPage County Jail until he provided blood samples. The samples were the only physical comparison available in 1985. They proved nothing definitive, but they did not exclude him either. For more than a decade, Dana Henry was the local suspect.

He was never charged. He was never cleared. He was simply a man the community had decided was probably guilty. Henry spent more than $50,000 on legal fees.

He lost his home. Friendships fractured. Relatives stopped returning calls. A man who had not killed anyone watched his life come apart for 16 years because his mother lived too close to a path.

In the year 2000, DuPage County established a dedicated cold case unit. The Wesselman file was one of the first they pulled. The crime lab still had the 1985 rape kit. By that year, forensic technology had advanced enough to extract a usable male DNA profile from the biological material the kit had preserved.

The lab succeeded. The profile was complete. It was uploaded to the FBI’s national database, the Combined DNA Index System, known as CODIS, and run against every offender on file. There were no matches.

Whoever Christie Wesselman’s killer was, his DNA was not yet in the system. The file went back on the shelf. Detective Buckholtz, by then, was approaching retirement. Other detectives took it up.

None of them got further. There was one detail in the field report from July 22nd, 1985 that no one would understand for another 13 years. Joe Birkett was the DuPage County State’s Attorney through the 1990s and into the early 2000s. He had not been the prosecutor on the original Wesselman case.

He had inherited the file when he took office. He had read it, and he had carried it. In the late 1990s, as DNA technology advanced, Birkett kept returning to one fact. The killer of Christie Wesselman had to be a repeat offender.

The brutality of the attack, the practiced violence of it, the speed of the assault on a public path in daylight—none of it suggested a first-time crime. Birkett believed the man who had killed Christie was almost certainly committing other felonies. He believed that if Illinois could simply require DNA from every convicted felon, not just from sex offenders, the killer’s DNA would eventually arrive in the system on its own. In the year 2000, Birkett began championing what would become the Illinois Felony DNA Mandate.

The proposed law required all convicted felons in the state to submit a DNA sample to the state database upon conviction. Drug offenses, theft, domestic battery—every felony, regardless of category. Civil liberties groups pushed back hard. They argued the law was government overreach.

They argued it expanded biometric collection beyond a reasonable scope. They argued non-violent offenders should not be treated as future violent offenders. Birkett and his allies in the legislature used the cold cases. They named Kristy Wesselman to the committee.

They named the time of day she had walked to a supermarket and the dirt path she had taken home. Birkett told reporters openly that he was fighting for the bill, in his own words, with Kristy Wesselman in mind. The bill passed in 2002. Illinois became only the second state in the country to require DNA submission from every convicted felon.

What Birkett predicted would happen—that the killer of Kristy Wesselman would eventually walk into the system on his own legs, on a charge unrelated to the murder—would in fact happen. It would take 13 more years. By the time it happened, Joe Birkett would no longer be the state’s attorney. He would have been appointed to the Illinois Appellate Court.

The case would be in other hands. The law would still be there. Across the state, the people who could have walked away from this case did not. They built the structure that would catch the man who killed her without knowing his name.

They knew that sooner or later his name would surface. It surfaced on September 10th, 2015. Before the breakthrough, there were 30 years of silence. A mother, a scholarship, an empty chair at a graduation, and one piece of evidence in a refrigerator waiting.

The years between 2000 and 2015 carried their own weight on the Wesselman case. In 2004, Sandy Wesselman sat for a television interview to mark the 20th anniversary of her daughter’s murder. She talked about Christie’s notebook. She talked about the path.

She asked anyone who knew anything to call the DuPage County tip line. The phones rang the next day. None of the calls led anywhere. In 2008, Glenbard South High School graduated the class that would have been Christie’s 23rd reunion year.

None of her former classmates organized anything official. Some of them were now parents of children of Christie’s age. A few of them drove back to the dirt path that summer. The path had been closed for years.

The undergrowth had grown over it. In 2010, the DuPage County cold case unit submitted the rape kit for a second round of testing on advanced technology. The new tests refined the profile. It still matched no one in the national database.

In 2012, Sandy Wesselman sat at a kitchen table in Glen Ellyn and watched another decade end without an answer. Her surviving children were grown. The house was quieter than it had been in 1985. She kept Christie’s notebook on a shelf.

She kept the pearl ring’s place on a small dresser, even though the ring itself had never come home. The silence had a sound. It is the sound of a refrigerator humming in a crime lab in Wheaton, Illinois. The sample is at the back.

The label on the bag is faded. The technician of 2012 has never met Sandy Wesselman. She does not know the file by name. She knows it by case number.

She has been told the case is still active in the way that all cold cases are still active. She walks past the sample twice a week. In Champaign, Illinois, a handyman named Michael Jones turned 60. In July of 2015, a 62-year-old man named Michael R.

Jones lost his temper with his wife. Jones lived in a small house on the south side of Champaign. He worked locally as a handyman. He had been doing handyman work in central Illinois for more than 30 years.

To his neighbors, he was a quiet, transient, blue-collar man who liked motorcycles and read paperback true crime novels. To his wife, on a Friday in July of 2015, he was something else. He attacked her violently enough that her injuries required medical treatment. The Champaign County Sheriff’s Office charged him with felony aggravated domestic battery.

Jones pleaded guilty. Under the Illinois law that Joe Birkett had spent two years fighting for in 2002, every convicted felon in the state was required to submit a DNA sample upon conviction. The sample was a buccal swab—a cotton swab rubbed against the inside of the cheek. It took a deputy in the booking area of the Champaign County Jail less than 30 seconds to collect Michael Jones’ swab.

The swab was sealed, logged, and mailed to the Illinois State Police Crime Lab. It arrived at the lab in late August. It was processed in early September. On September 10th, 2015, the Illinois State Police database returned a match between the profile from Jones’ buccal swab and an unidentified profile from an unsolved 1985 rape and homicide in DuPage County.

The match was at every locus tested. The probability calculation was the kind of number that no longer felt like a number: one in one and a half quadrillion. To find a second person with the same genetic profile, investigators would have to search a population approximately 187,000 times the size of Earth. The DuPage County State’s Attorney’s Office was notified within hours.

State’s Attorney Robert Berlin was briefed. So was Detective Buckholtz, who was by then long retired, but still receiving updates on the case. The investigators ran a second verification. They pulled Jones’s record.

They learned that in 1977, at the age of 23, Jones had been convicted in Cook County of using his vehicle to ram a 26-year-old woman named Jeri Michael off her bicycle, abducting her at gunpoint, driving her to his parents’ house in Schiller Park, and repeatedly assaulting her. He had been sentenced to 10 to 20 years. He had served less than seven. He had been paroled in 1983.

Jeri Michael had not been notified of his release. By July of 1985, Michael Jones was a free man on parole, living in central Illinois, traveling on weekends to the Chicago suburbs to visit family near the Wisconsin border. The route between Champaign and that family’s home ran directly past Glen Ellyn. On September 18th, 2015, the DuPage County Sheriff’s Office executed a search warrant at Jones’s home in Champaign.

They took a second buccal swab to verify the database match. They placed him under arrest. They charged him with first-degree murder and aggravated criminal sexual assault. When they showed him a photograph of Kristy Wesselman, he looked at it for several seconds.

Then he said, “As God is my witness, I’ve never seen her before. ”

The mathematical certainty did not require a confession. It did not require him to remember her. It did not require him to admit what he had done.

It required only that the genetic markers tested in 2015 match the genetic markers preserved in the crime lab refrigerator since the morning Detective Kevin Buckholtz had found Kristy’s body in the weeds. One in one and a half quadrillion. The cold case was solved by a felony domestic battery in a town nobody had connected to Kristy Wesselman in three decades. Dana Henry, the local man whose mother had lived 100 yards from the dirt path, the man who had lost his home, $50,000, and most of his friends to a suspicion that had hardened into local certainty, had never been the killer.

Not in 1985. Not at any point since. The killer had been a handyman two hours south. He had not been interviewed in 1985.

His name had appeared on no tip from the original investigation. Glen Ellyn had never heard of him. Sandy Wesselman was called by the State’s Attorney’s office on the morning of September 18th. She was told to sit down.

She had been waiting 30 years, 1 month, and 28 days. Between his arrest in September of 2015 and his plea in January of 2018, Michael Jones sat in the DuPage County Jail. He waited for a trial. Prosecutors prepared one.

They prepared aggressively. They filed a motion to introduce five women Jones had assaulted before 1985, including Jeri Michael, as evidence of his propensity for sexual violence. The motion was granted in part. The women included those whose cases had never been charged for lack of physical evidence at the time of the assaults.

Sitting in his cell awaiting that trial, Jones picked up a Styrofoam coffee cup. He wrote five words on the side of it: I’m sorry for 1985. A guard logged the cup. Prosecutors took it as evidence.

It was the closest thing to a confession Michael Jones ever produced. On January 23rd, 2018, he pleaded guilty to first-degree murder and aggravated criminal sexual assault. He did not detail the timeline. He did not explain what had brought him to Glen Ellyn that Sunday afternoon.

He did not say her name in court. He pleaded. At the sentencing hearing that same day, the courtroom in Wheaton was full. Jeri Michael, 66 years old, stood and addressed the man who had abducted her at 26.

She told the court what he had taken from her. She told the court what he had done to a 15-year-old girl eight years after the system let him out early on her own sentence. Sandy Wesselman stood next. She did not raise her voice.

She read from a single sheet of paper. She told the court that her daughter’s life had been a great book, and that what Christie would have become—the New York apartment, the practice, the children she would have helped—will forever be an unfinished book. Judge George Bakalis looked at Michael Jones. He used a phrase that does not usually appear in sentencing remarks.

He called him evil incarnate. He sentenced Jones to 80 years in prison. Under the statute applicable to the 1985 offense, Jones must serve every day of the 80 years. He was 64 years old.

He will not leave prison alive. Outside the courtroom, the Glenbard South Class of 1988 announced they were reinstating the Kristy Wesselman Memorial Scholarship. The pearl ring her grandmother had given her was never recovered. Sandy Wesselman still keeps a notebook in a drawer in Glen Ellyn.

It is full of vocabulary words a 15-year-old girl wrote down as she taught herself to write better. It is full of sentences from a college essay she would not live to send. Kristy Wesselman would have been 56 years old this year. She would have been a child psychologist in New York.

There would have been an ordinary life—the kind of freshman class president who played basketball, volleyball, and softball was already at 15 working to build. There was instead a candy bar with one bite taken out of it, a dirt path through the weeds, and a mother who had held the rest of the book for 40 years. Michael Jones served less than 7 years for a brutal 1977 rape. Had he served the full 20 years the sentencing judge had imposed, he would have been behind bars on July 21st, 1985.

Whether Illinois has reformed its parole system enough since 1983 is a question other cases will eventually answer. Whether Joe Birkett’s law has caught the killers it was designed to catch is a question already being answered, one buccal swab at a time.
