CPD identifies deceased former detective as 1960 child killer through family-tree DNA

Summary

The Chicago Police Department’s Monday identification of Thomas McInerney, a former homicide detective who joined the force in 1959 and retired in 1987, as the killer of eight-year-old Gloria Kowalewicz in November 1960 closes a 65-year investigation and produces an accountability gap acknowledged by the agency itself and by the victim’s surviving brother.
The identification relied on DNA submitted to a family-tree website that enabled an FBI match, with further DNA, fingerprint, and ballistic testing corroborating the determination, according to the CPD.
McInerney died on August 30, 2006, at age 70, two decades before the identification was made public, and Gloria’s parents died without learning who killed their daughter, according to the CPD.
The CPD, in materials available to the source, did not address why McInerney was not surfaced as a person of interest during his 27-year tenure, and the substrate does not document his conduct between 1960 and his 1987 retirement beyond the obituary’s “numerous commendations.”

The Chicago Police Department on Monday identified Thomas McInerney, a former CPD homicide detective and U.S. Army veteran, as the man who abducted and fatally shot eight-year-old Gloria Kowalewicz on November 12, 1960. McInerney, who lived around the corner from the Kowalewicz family, had joined the Chicago force the year before the killing. He died in 2006 at age 70, two decades before authorities made the identification public, foreclosing any legal accountability channel for a crime now resolved through forensic means rather than adversarial testing of evidence. The agency’s Monday statement observed that Gloria’s parents died without ever learning who had murdered their daughter. Adam Kowalewicz, the victim’s brother, told the Chicago Tribune that McInerney “never paid his dues,” and added: “You hope he’s going to pay his dues with the good lord.” The CPD, in its own statement, acknowledged that “it is devastating to accept that he was never identified and held accountable while he was alive.”

The procedural record: 1960 to 2026

Gloria Kowalewicz was last seen alive on the morning of November 12, 1960, walking from her family’s West Englewood home to a nearby church for mass, according to a CPD statement released Monday. She was abducted along the way and fatally shot; her body was found hours later in a ditch at a forest preserve southwest of the city. Investigators at the scene recovered several pieces of evidence — including a bullet, her coat, and a white communion purse containing a prayer book — and lifted a fingerprint from the strap of that purse, the source reports.

The 1960 investigation mobilized a task force joined by firefighters, Boy Scouts, and military veterans in the days after Gloria’s death. The task force interviewed about 1,300 people and administered a dozen lie-detector tests, but identified no suspect at the time.

The 2026 identification proceeded through a different mechanism. The Chicago Tribune, which first reported the development in a lengthy Sunday article, reported that DNA submitted to a family-tree website enabled the FBI to match McInerney to the scene. Further DNA, fingerprint, and ballistic testing established McInerney as Gloria’s killer, the CPD said. The agency’s Monday statement said it hoped the news “brings a measure of closure to all who knew Gloria and her story.”

The substrate does not name the family-tree platform, does not name the submitter, does not give the submission date, and does not address the legal pathway by which the FBI obtained the DNA match or the consent framework governing the submission.

McInerney’s documented tenure: 27 years inside the institution

McInerney joined the Chicago force in 1959, according to his obituary, published after his death on August 30, 2006. He was about to turn 25 at the time of Gloria’s murder. He retired from the agency in 1987 as a homicide investigator, then worked as an investigator for the federal public defender’s offices in Las Vegas and Reno, retiring from those positions in 2004. His obituary cited “numerous commendations during his years with the [CPD]” and noted he had been recognized as outstanding federal defender investigator in 2003. He was survived by his wife, two sons, three daughters, and a dozen grandchildren.

The CPD’s Monday statement characterized McInerney’s service in stark terms: “McInerney should have never worn the CPD star.” The agency described the killing as “abhorrent,” and added that the perpetrator “not only took the life of an eight-year-old child – but left … all who knew and loved her shattered as they searched for answers.”

The substrate does not document McInerney’s conduct between 1960 and his 1987 retirement beyond the obituary’s commendations and the 2003 federal-defender recognition. The CPD, in materials available to the source, did not address why McInerney was not surfaced as a person of interest during his 27-year tenure, despite his having lived around the corner from the Kowalewicz family at the time of the killing and having served on the same force that investigated the case.

Who benefits: documented positions per party

The substrate documents positions for three principal parties. The Kowalewicz family, in the only on-record family statement, characterized the identification as “a relief,” according to Adam Kowalewicz’s remarks to the Chicago Tribune, while also expressing frustration that McInerney had died without being made to face justice.

The Chicago Police Department’s Monday statement expressed the agency’s hope that the news “brings a measure of closure to all who knew Gloria and her story,” and observed that Gloria’s parents “died without ever learning who had murdered their daughter.” The statement explicitly named the accountability gap, characterizing it as “devastating.”

McInerney’s family is named in his obituary but has not issued a public statement on record in the source material or the CPD’s Monday statement; the substrate does not establish whether one has been or will be issued.

The case also supplies one to other cold-case families as a methodological precedent. The resolution combines family-tree DNA submission, FBI matching, and fingerprint and ballistic corroboration — a chain that the original investigation’s 1,300 interviews and dozen polygraphs did not produce.

For the family-tree database industry and contributors, the case is one publicly reported instance of law enforcement using uploaded genetic data to identify a deceased perpetrator. The substrate does not characterize the industry’s response or that of database contributors.

How this is being framed

The substrate supplies three documented frames for the unresolved institutional question of how an officer operating from within the institution evaded detection for 27 years. The substrate does not support a determination among them.

One frame concerns institutional non-detection. McInerney lived around the corner from the Kowalewicz family, joined the CPD the year before the killing, and held investigative roles through 1987. The 1960 investigation interviewed approximately 1,300 people and administered a dozen polygraphs without surfacing him. The substrate does not state why he was not surfaced, and the agency did not, in materials available to the source, address the question.

A second frame concerns the forensic methodology. The 1960 investigation relied on interviews and polygraphs; the 65-year identification came only after DNA submitted to a family-tree website enabled the FBI match, with further DNA, fingerprint, and ballistic testing. The mechanism is now demonstrated in a documented case involving an officer rather than hypothetical.

A third frame concerns physical-evidence handling across decades. A fingerprint was lifted from the communion-purse strap in 1960. The substrate records that the 2026 identification also relied on fingerprint testing but does not address whether the 1960 fingerprint was retained, re-tested, or matched only at the end of the investigation. The substrate records no public accounting of what the agency did with the physical evidence between 1960 and 2026.

The CPD’s Monday statement, which framed the matter as one of unfitness-to-serve, is voiced by the same institution that employed McInerney for 27 years. The substrate records no competing public framing against that institutional characterization.

What happens next: consequences and sequel

In the immediate term, the Kowalewicz family has received forensic confirmation of the killer’s identity — a resolution that reaches a generation removed from the original loss. McInerney’s 2006 death forecloses any legal accountability channel: the formal determination rests on law-enforcement findings rather than adversarial testing of evidence, and the substrate documents no defense counsel, no independent fact-finder, and no procedural avenue for the family or estate to contest the identification.

In the short term, the case is likely to inform debates over the investigative use of genetic data submitted to family-tree websites. The method now joins conventional evidence types in one resolution that the 1960 investigation did not produce. The substrate records no statement from the federal public defender’s offices in Las Vegas and Reno, where McInerney worked between 1987 and 2004; no statement from neighboring jurisdictions; and no statement from the FBI on the methodology’s broader use.

In the medium term, the case documents one instance in which the method has resolved an investigation in which the perpetrator operated from within the institution. The substrate does not record comparable prior cases; whether the Kowalewicz resolution is methodologically representative of broader capability is a question the substrate does not address. Whether the next CPD-era cold case solved by a family-tree DNA match lands on a current or former employee, or on a stranger to the department, will be a further test the substrate cannot pre-resolve.

In the long term, the case contributes to a documented record of investigations in which perpetrators died before identification. For database contributors and privacy advocates, the case intensifies existing debates the source does not engage with directly.

A structural feature of the determination deserves noting: the evidentiary chain (DNA match via family-tree submission → FBI confirmation → CPD fingerprint and ballistic corroboration) was assembled and announced by the same law-enforcement apparatus that employed the deceased for nearly three decades, and the agency’s own characterization — “McInerney should have never worn the CPD star” — is voiced by the same institution that employed him.

Additional considerations

Several questions remain open in the substrate.

The family-tree platform identity, submitter identity, and submission date are not on record. There is no on-record account of any CPD review of cases McInerney touched as a homicide investigator, nor of any review by the federal public defender’s offices in Las Vegas and Reno of matters he touched between 1987 and 2004. McInerney’s conduct record between 1960 and 1987, beyond the obituary’s “numerous commendations” and the 2003 federal-defender recognition, is not documented in the substrate. The legal pathway by which the FBI obtained the DNA match and the consent framework governing the family-tree submission are not addressed.

The substrate does not document competing public attitudes toward the identification or toward the use of genetic data submitted to family-tree websites for law-enforcement matching; the only public-facing material the substrate records is the CPD characterization and Adam Kowalewicz’s quoted remarks. The disposition of the 1960 fingerprint and other physical evidence between 1960 and 2026 has not been publicly accounted for by the CPD in the materials available. A fuller assessment of the gap between McInerney’s cited record and the determination would require evidence the substrate does not supply: CPD personnel records, successor investigation, or comparable case data.
