The Starved Rock Murders — 1960 Illinois triple homicide

The Case

The Starved Rock Murders are a 1960 American triple homicide in which three middle-aged women from suburban Chicago were beaten to death during a hiking trip in Starved Rock State Park, Illinois. The case ended in the conviction of 21-year-old lodge dishwasher Chester Otto Weger, but it has remained one of the most disputed American murder cases of the twentieth century because Weger maintained his innocence until his death in 2025 and later DNA work excluded him from key physical evidence.

The Crime

In March 1960, three friends from Chicago's affluent Riverside neighborhood — Lillian Oetting, Mildred Lindquist and Frances Murphy — traveled to Starved Rock State Park for a four-day getaway. They checked into the park lodge near Oglesby, Illinois, and set off on a hike that they never completed. On March 14, 1960, their bodies were found inside a cave-like overhang in St. Louis Canyon, one of the park's deep sandstone gorges.

The scene was extraordinarily violent. Two of the women were found naked from the waist down, and each victim had been bludgeoned more than 100 times, reportedly with a heavy tree branch found nearby. Contemporary press accounts and later summaries discuss the possibility of sexual assault, but the sources used for this article do not confirm a proved rape finding. What is undisputed is the brutality: a triple homicide in a state park, carried out in broad daylight on a popular trail.

The Victims

Lillian Oetting and Mildred Lindquist were both 50 years old; Frances Murphy was 47. All three were married women from Chicago's western suburbs, part of the social circle around Riverside, and were described in reporting at the time as respectable, well-off friends taking an off-season nature break. Their deaths shocked Illinois and prompted a massive manhunt, with the park itself becoming forever associated with the killings — a fact that still shapes how the site is remembered today, as detailed by A&E's case feature.

Investigation

Investigators initially had little to work with beyond the crime scene itself. Attention eventually turned to staff at Starved Rock Lodge, where Chester Weger — an ex-Marine, married father of two, and dishwasher — worked. After months of questioning, Weger was arrested in November 1960. Prosecutors said he had confessed and even led officers to elements of the scene; Weger later said the confession was coerced after prolonged interrogation.

The physical case against him was thinner than the confession suggested. According to later reporting, there was no DNA evidence tying Weger to the crime scene, and he had passed six polygraph examinations during his decades-long campaign for exoneration. In 2022, post-conviction testing of a hair recovered from a glove worn by Frances Murphy reportedly excluded Weger as a contributor. In March 2024, Weger's attorney told reporters that genetic genealogy work pointed instead toward a member of the Bray family, a claim covered by ABC7 Chicago's reporting on the case.

Trial and Verdict

Weger went on trial in early 1961. On March 3, 1961 — his 22nd birthday — a jury found him guilty and fixed his punishment at life imprisonment, rejecting the prosecution's request for the death penalty. He was formally sentenced on April 3, 1961. Wikipedia notes that he was convicted of the murder of one of the three women, while ABC7 summarizes his conviction as being for the killing of Lillian Oetting, with accusations covering the deaths of the other two. He would spend nearly six decades behind bars, repeatedly denied parole before finally being released in 2020.

Today

The Starved Rock Murders are legally classified as solved — there was a conviction, a sentence and decades of incarceration — but they are publicly contested. Weger died on June 22, 2025, still insisting he was innocent. The combination of his recanted confession, the lack of DNA linking him to the scene, the 2022 exclusionary hair result and the 2024 genealogy claim has kept the case alive in American true-crime discussion, including in detailed video retrospectives on YouTube. For visitors to Starved Rock State Park, St. Louis Canyon remains both a natural landmark and the site of one of Illinois' most haunting unresolved arguments about guilt and justice.
