Bruce Lindahl died in Naperville, Illinois, on April 4, 1981, in an incident in which an 18-year-old, Charles Huber Jr., also died. The DuPage County State's Attorney attributes Huber's death to him. Because Lindahl was dead there was nobody to charge, and for almost four decades the matter rested there. Lindahl had been arrested repeatedly during the 1970s, but he had never been convicted of a felony, and complaints other women made to police were not pursued.
In January 2020 the DuPage County State's Attorney, Robert Berlin, announced that DNA evidence had identified Lindahl as the person responsible for the death of 16-year-old Pamela Maurer of Woodridge in January 1976. In October 2024 the Kane County State's Attorney and the North Aurora Police Department announced the same for the 1979 death of 19-year-old Kathy Halle. Prosecutors and detectives also say they suspect him in other deaths, among them that of Debra Colliander, a woman who had been due to testify against him. A detective has spoken of as many as 12 killings.
None of this was ever tested in court. Lindahl was never tried, never convicted and never had the chance to answer. Each killing in the record is therefore an attribution: it is what a State's Attorney, a police department or a detective has said the evidence shows. The record divides into what rests on a DNA comparison, what rests on a prosecutor's belief, and what remains only a detective's suspicion.
Lindahl grew up in the Downers Grove, Lisle and Woodridge area of DuPage County, west of Chicago. A December 1976 court record cited by the Daily Herald gives his birthplace as St. Charles. The ages given for his death differ slightly between outlets: the Daily Herald and CBS Chicago gave 28, while the Associated Press gave 29. The DuPage County announcement put him at 23 at the time of Pamela Maurer's death in 1976. Little else is known of his early years: his parents and siblings have not been named publicly, and his school years appear mainly in the recollections of former classmates in a later documentary.
A Chicago Tribune report from the time, cited by the Daily Herald in 2020, said he worked as a small-engine repair instructor at a vocational school in Kaneville. An Associated Press profile in January 2020 quoted Lisle Police Detective Chris Loudon describing him as a loner who moved often and had few close friends, and as a smooth talker. Investigators who spoke to the makers of a television documentary described him as a charismatic young man who could charm women and who also had a violent temper. A friend of his, an Aurora police officer, told the documentary makers that Lindahl liked to show friends slideshows of women he had met. The officer was not charged with anything.
The coverage places him in the western suburbs for his whole adult life. A 2024 Forensic magazine account of the North Aurora investigation says he lived in Chicago and its suburbs and moved to Aurora in 1978. According to Detective Loudon, he lived in the area around Downers Grove, Lisle and Woodridge before that. Lisle investigators spent about three months mapping unsolved deaths of the period and said, in an interview with CBS Chicago, that the locations clustered around the places where he was known to have lived.
The police files that survive show a man who was arrested again and again and never held. According to the 2024 Forensic magazine account, he was arrested repeatedly from 1974 onward, and each time he was fined or released on bail. The AP reported in 2020 that police had known him as someone arrested many times but never convicted of a felony. A Patch report from January 2020 said his archived police record showed charges but no convictions, and quoted Detective Loudon as saying that there were "a couple other police reports." In December 1976 a court record in Woodridge named him in a minor offense, the Daily Herald noted; the entry is a small one, but it places him in Woodridge in the year of the first death later attributed to him.
Detective Loudon has said the failure to stop him was partly a failure of belief. He told the Daily Herald in 2023, in coverage of the documentary, that police in that era did not pursue complaints other women made about Lindahl, and did not take seriously the families of young women who had died or were being sought. In his words, those women and families "felt like no one cared." He added that Lindahl "should have been caught way earlier." A police report from the Maurer inquiry records Lindahl telling officers that he had known Maurer through a girlfriend, and Loudon said officers overlooked him when they questioned people near her home.
The Forensic magazine report describes a complaint made to Aurora police in March 1979 that was not believed, and calls it a missed chance to identify him. Kathy Halle died in North Aurora later that same month.
Pamela Maurer, who was known as Pam, was 16 and lived in Woodridge, Illinois. The DuPage County State's Attorney's Office gave her age as 16; some later Daily Herald stories gave 15. In January 1976 she died in Lisle, the next suburb over, and her death was treated as a homicide. Lisle police and Woodridge police investigated and collected biological evidence, but the case went cold.
M.J. Wurth, who was Lisle's police chief at the time, said in the years afterward that investigators would probably never learn why she was killed, but that they would find the person responsible. The case was reopened in 1993 after new information came in, according to Patch, and no charges followed. The family later moved to Texas.
Her friends carried the loss for the rest of their lives. At the January 2020 news conference a friend, speaking afterward to reporters, said it was a relief to her and to Maurer's other friends that the person responsible had been a stranger. Detective Loudon, who had spent years on the case, said simply that he was glad for Pam.
Biological evidence from the 1976 inquiry was kept. In 2001 it was analyzed at the DuPage County Sheriff's Crime Laboratory, and a DNA profile of the person who left it was developed and entered into the national database known as CODIS. It matched no one. That outcome was not surprising in hindsight: Lindahl had never been convicted of a felony, so his DNA was never taken and never entered into any database.
The case sat for most of two more decades. Detective Loudon, who joined the Lisle department and was assigned three cold cases, solved two of them, involving crimes against elderly women, in 2014 and 2017. The third was Maurer's. Lisle police considered it unsolvable, Loudon told the Daily Herald, and he wondered whether newer DNA technology could identify a suspect from the stain that had been preserved.
In 2019, at the request of the Lisle Police Department and the DuPage County State's Attorney's Office, the evidence went to Parabon NanoLabs, a company in Maryland. Parabon produced a "snapshot" predicting the physical traits of the unknown person: eye color, hair color, skin color and face shape, along with a composite image. CBS Chicago reported that the composite resembled Lindahl. State's Attorney Berlin described the snapshot as an approximation of the unknown subject, a prediction and not a photograph.
The more decisive step was genealogical. Parabon's chief genetic genealogist, CeCe Moore, told CBS Chicago that her team compared the DNA with a public database, GEDmatch, found distant cousins of the unknown person, up to about 20 matches, and built family trees back to a common ancestor. A likely candidate emerged within a few days, she said. The tree led to a family of four brothers, two of whom had lived in Downers Grove at the time of the death, the Daily Herald reported in 2023. Authorities called it the first murder case in Illinois solved through investigative genetic genealogy. Lindahl was not an original suspect, Loudon said.
A family tree does not name a killer; it points to a family. Investigators needed a sample from Lindahl himself. According to the documentary coverage, a relative refused to provide DNA, so Loudon sought a court order to obtain a sample directly from Lindahl. The order was granted, and in November 2019 investigators from Lisle police, the DuPage County Sheriff's Office, the DuPage County Coroner's Office and the State's Attorney's investigations division collected the sample. Patch gave the date as November 6, 2019. The DuPage County Sheriff's Crime Laboratory and a Florida company, DNA Labs International, produced a profile from it.
The profile was consistent with the DNA recovered from Maurer. Berlin told reporters that the chance a random person would be included as a contributor was one in 1.8 quadrillion. Because Lindahl had never been tried, the statement that he was responsible is the State's Attorney's own conclusion from that comparison. It was reached after his death, with no defense and no court hearing, and it should be read that way.
Investigators went to Texas to tell Maurer's father and brother before the public announcement. Loudon said the family had shown a great deal of relief.
On Monday, January 13, 2020, Berlin held a news conference in Wheaton. The DuPage County State's Attorney's Office announced that Bruce Lindahl of Aurora was responsible for the 1976 killing of Pamela Maurer. Berlin said the case was the first in Illinois solved with investigative genetic genealogy, and he credited the many officers from several agencies who had kept it open. "Today, that mystery has finally been solved," he said, according to CBS Chicago.
Berlin did not stop at Maurer. He said the State's Attorney's Office had evidence that Lindahl might have harmed other women from about 1974 until his death in 1981, and that his DNA profile would now be used to review unsolved cases. "Pam was not Bruce Lindahl's only victim," he said. He asked anyone who might have been a victim to come forward, and tip lines were opened at his office and at the Lisle Police Department.
Detective Loudon told reporters, "I suspect him to be a serial killer." The phrase is his, and it is a suspicion, not a finding. Loudon said other cases were being worked by other departments in which he regarded Lindahl as a solid suspect. Within a day he had told the Associated Press that Lindahl might have killed as many as 12 young women and that investigators knew of nine cases so far, a figure he said could rise from nine to 12. CBS Chicago reported on January 15 that investigators believed Lindahl was responsible for at least 12 people's deaths, of whom only four had until then been confirmed; Kendall County Detective Sergeant Caleb Waltmire said "up to 12." The reports differ on what the numbers count. ABC7 reporting in 2024 repeated the figure as as many as 12 murders in the western suburbs. These are investigators' estimates, not charges and not findings.
The AP account also recorded Loudon's observation about a pattern in the geography: deaths in the Lisle area stopped after Lindahl moved toward Aurora, and cases began to occur closer to his new home.
Debra Colliander was 25 and lived in Aurora. Patch described her in 2020 as a native of Wisconsin. In June 1980 Lindahl was arrested and charged in Aurora with aggravated kidnapping and other offenses against a young woman, who was Colliander. Lindahl was released on bail, and a trial date was set.
A friend of Lindahl told police that Lindahl had said that if Colliander did not appear in court, he would get out of the charges, Berlin said. Years later, Berlin told WSPY and other outlets that the friend had also said Lindahl offered him money and other items to "get rid of" her. The friend never acted on the offer and did not tell police about it until later.
The charges were dismissed in March 1981, when the key witness could not testify, WSPY reported on speedy-trial grounds. After Lindahl had died, the Kendall County coroner ruled Colliander's death a homicide; the cause could not be determined.
Berlin said that all the evidence pointed to Lindahl and that Colliander was probably killed to keep her from testifying. He said Lindahl might have hired someone or acted alone. Kendall County Sheriff's deputies investigating the case said no usable DNA from her killer was preserved, and Waltmire told CBS Chicago that this made proof difficult. So the attribution of her death to Lindahl rests on motive, on the friend's account and on the timing, not on forensic evidence, and it remains a suspicion as stated by prosecutors.
Lindahl died in Naperville on April 4, 1981. Naperville's police chief Robert Marshall, then a patrol officer, was among the officers who responded. The incident was one in which an 18-year-old, Charles Huber Jr., a resident of Naperville, also died. Investigators first thought they were looking for a killer at large, Marshall told the Daily Herald in 2020. The DuPage County State's Attorney attributes Huber's death to Lindahl.
Marshall described the matter as perplexing. Because Lindahl was dead there was no one to charge, and, Marshall said, "justice can be delivered in many different ways."
Loudon told the documentary makers that the evidence from the Naperville case is no longer available. Naperville police did keep a box of Lindahl's belongings, which turned out to matter in the later North Aurora investigation.
The attribution of Huber's death to Lindahl comes from the DuPage County State's Attorney's Office and from Naperville police. Statements from Huber's family were not reported. No trial or inquest decision on the matter was reported; the case closed with Lindahl's death.
Kathy Halle was 19 and lived in North Aurora. She died in March 1979. Her case stayed open for 45 years.
The Kane County State's Attorney later laid out the sequence of tests. In 2000 the Illinois State Police tested DNA from the case and got no result. In 2020, after Lindahl was named in the Maurer case, the evidence went to the DuPage County forensics laboratory, which found a mixture of DNA from two people, too degraded to identify anyone. In 2020 the North Aurora department reopened the case. In 2022 Detective Ryan Peat learned of a collection method called the M-Vac System, which extracts DNA from fibers and other porous material. In December 2022, the department learned that Naperville police still held the box of Lindahl's belongings, and some items in it placed him in Aurora near the time of the killing, according to Forensic magazine.
A grant of about $10,000 from a nonprofit, Season of Justice, paid for the work. The evidence went to DNA Labs International in Florida in 2023. In August 2024 the laboratory reported that the DNA on Halle's clothing was 9.4 trillion times more likely to have come from Lindahl than from an unrelated person, Forensic magazine reported.
North Aurora police and Kane County State's Attorney Jamie Mosser announced the result at a news conference on Wednesday, October 23, 2024. Mosser said her office would have authorized first-degree murder charges had Lindahl been alive, and that the case "would have been charged in a court of law had Bruce Lindahl not died in 1981." She said his "patterns and practices" were why he had become a suspect. Peat said the identification "doesn't save Kathy" and does not bring justice to Lindahl. North Aurora Police Chief Joseph DeLeo said advances in forensic technique made it possible to find new evidence and bring closure to families. Deputy Chief Joe Gorski read a message from Halle's family, who said, through a liaison officer, that they were grateful to have closure after 45 years, and who asked reporters not to contact them.
WSPY reported that Halle would be the third person law enforcement had confirmed Lindahl killed.
Beyond Maurer, Halle and Colliander, the officials' lists are less firm.
Deborah McCall, of Downers Grove, is another 1979 case. Her age is given as 16 in the 2020 Daily Herald and Patch coverage and as 19 in the Daily Herald in 2023 and 2024. The case has not been resolved. Berlin said he believed Lindahl was involved, and Loudon has said he hopes someone will come forward with information about her.
Elizabeth Drews of Downers Grove died in 1977. Her age appears as 16 and as 17 in different Daily Herald stories. Berlin has named Lindahl as a suspect in her death, and Loudon lists her among the cases he believes are linked.
Susan Jabczynski, 21, died in 1980. The Daily Herald places her in Aurora; WSPY says she was from Grand Ridge and lived in Oswego. A retired Lisle detective suspects Lindahl was involved, and Loudon includes her on his list.
Loudon told the Daily Herald in 2023 that two more women are on his list whose names he is not permitted to give, and that he believes "there is way more than nine." The Daily Herald reported in 2026 that a Will County spokesman said Lindahl had been ruled out as a suspect in the 1976 death of Jennifer Springman, 17, a case that had at times been mentioned alongside his.
The story of the Maurer investigation became a television documentary, The Box, which aired in Great Britain in 2022 and reached the Topic streaming service in the United States on June 8, 2023. The Daily Herald's review of it drew on interviews with Loudon and with Lindahl's former classmates at Downers Grove North. It followed investigators as they went through a box of evidence from another police department. That box, Loudon said, was what persuaded him he was not dealing with a single death.
The Daily Herald noted that most of the detail came from Loudon's own account and the film, and that the newspaper had not verified it independently.
Three tiers run through the record, and the public statements are not always careful about the difference.
The first is a DNA comparison announced by a State's Attorney. For Pamela Maurer, the DuPage County State's Attorney's Office announced a profile from the 1976 evidence consistent with DNA taken from Lindahl, with a stated random-match figure of one in 1.8 quadrillion. For Kathy Halle, the Kane County State's Attorney's Office and North Aurora police announced a laboratory result of 9.4 trillion times greater likelihood that the DNA on her clothing came from Lindahl. In both cases prosecutors said they would have brought charges, or in Maurer's case named him as responsible, had he lived. Neither claim was tested at a trial.
The second is a prosecutor's belief resting on circumstance. Debra Colliander was due to testify against Lindahl at a trial, a friend described his offer, and the charges ended for want of a witness. Berlin said all the evidence pointed to Lindahl. No forensic link was reported, and Lindahl might have acted alone or through someone else, in Berlin's account.
The third is a detective's suspicion, as in the cases of Drews, Jabczynski, McCall and others. Loudon has been open about it. Investigators have spoken of nine known cases and as many as 12 killings, but the counts differ between outlets and no list of 12 named victims has been published.
Some details differ from one account to another. Lindahl's age at death is 28 in some reports and 29 in the AP. Maurer was 16 in the DuPage announcement and 15 in some Daily Herald pieces. McCall was 16 in some accounts and 19 in others. Drews was 16 or 17.
Loudon's account is that complaints made to police about Lindahl in those years were on file and were not acted on.
Maurer's father and brother, then living in Texas, were told in person before the announcement. Halle's family, through the North Aurora police liaison, thanked investigators and asked for privacy. Statements from the family of Charles Huber and from Colliander's relatives were not reported.
Peat's remark at the 2024 news conference sums up the limit of what a late identification does. He said it does not save the victim, and with Lindahl dead it brings no justice to him. Marshall, the Naperville chief, took a more hopeful line: his own takeaway, he said, was that officers never give up on unresolved cases.
Lindahl has been dead since April 1981 and cannot be charged. Through 2026, the two DNA-based attributions, to the DuPage County State's Attorney's Office (Maurer, January 2020) and to the Kane County State's Attorney's Office (Halle, October 2024), stand as announced, and the Colliander case remains an open Kendall County matter with no forensic link. The McCall case has not been resolved. A 2026 Daily Herald report on the 50th anniversary of the Springman case recorded a Will County spokesman saying Lindahl had been ruled out in that case.
