Case overview
On May 21, 1924, 14-year-old Bobby Franks was abducted and killed in Chicago by two wealthy University of Chicago students who believed they could commit the perfect crime. Nathan Leopold and Richard Loeb confessed within days, but their trial became a national spectacle that exposed gaps in motive, conflicting psychiatric testimony, and a public desperate to understand why two privileged young men would kill a neighbor’s child for intellectual gratification.
The victim and the abduction
Robert “Bobby” Franks was the son of Jacob Franks, a wealthy Chicago watch manufacturer. The family lived in the affluent Kenwood neighborhood on the South Side, where many of the city’s prominent Jewish families had settled. Bobby attended the Harvard School for Boys and was known as an athletic, well-liked student.
On the afternoon of May 21, Bobby was walking home from school when he was offered a ride by two men he recognized from the neighborhood. Nathan Leopold, 19, and Richard Loeb, 18, were both graduates of the University of Chicago and sons of wealthy families. Loeb’s father was a vice president of Sears, Roebuck and Company. Leopold’s father was a box manufacturer.
Bobby accepted the ride. Within minutes, he was struck in the head with a chisel, gagged, and killed. His body was driven to a remote culvert near Wolf Lake, about 20 miles south of Chicago, stripped, doused with hydrochloric acid to obscure identifying features, and hidden in a drainage pipe. The killers then attempted to collect a $10,000 ransom from Bobby’s father by mailing detailed instructions and making a phone call that evening.
Discovery and investigation
Bobby Franks’ body was discovered the next morning by a laborer walking near the culvert. Police identified the victim quickly through dental records and clothing fragments. The ransom note, signed with the alias “George Johnson,” was still in transit when the body was found.
Investigators recovered a pair of eyeglasses near the body. The frames were common, but the hinges were an unusual patented design sold by only one Chicago optician. Police traced the glasses to three customers, one of whom was Nathan Leopold. When questioned, Leopold said he had been birdwatching in the area and must have lost them. He provided an alibi: he and Loeb had been driving around in Leopold’s car, picking up two women whose names they could not recall.
The alibi collapsed when Leopold’s family chauffeur told police that Leopold’s car had been in the garage for repairs on May 21. Loeb’s chauffeur also contradicted their timeline. Confronted separately, both men confessed within hours, each blaming the other for the actual killing. Their confessions were made without legal counsel present and were published in full by Chicago newspapers the following day.
The planning and motive
Leopold and Loeb had spent months planning what they called “the perfect crime.” Both were intellectually gifted students who had graduated from college early and considered themselves superior to societal norms. They had studied Friedrich Nietzsche’s philosophy and believed they embodied the concept of the “superman,” exempt from conventional morality.
They had previously committed minor thefts and arson for thrill. The murder of Bobby Franks was intended as the culmination of their experimentation. They rented a car under a false name, scouted locations, prepared ransom materials, and selected a victim at random. Bobby Franks was not specifically targeted. He was simply a convenient choice because he lived nearby and could be lured easily.
The question of which man struck the fatal blow was never definitively resolved. Both confessions placed the other in the back seat with Bobby at the moment of the attack. Loeb claimed Leopold hit the boy. Leopold said Loeb did. The physical evidence did not clarify the matter, and both men later recanted portions of their confessions while maintaining overall responsibility.
The trial and Clarence Darrow’s defense
The case went to trial in July 1924. Because both defendants had confessed, the question was not guilt but punishment. Illinois law allowed the death penalty for murder, and public sentiment overwhelmingly favored execution. The Chicago press covered the case daily, publishing psychiatric evaluations, courtroom sketches, and opinion columns debating the nature of evil and responsibility.
Clarence Darrow, one of the most prominent criminal defense attorneys in the country, agreed to represent Leopold and Loeb. He waived a jury trial and argued directly before Judge John Caverly, presenting a defense based on diminished responsibility. Darrow did not dispute the facts of the crime. Instead, he argued that the defendants’ youth, psychological development, and emotional immaturity should preclude the death penalty.
Darrow introduced psychiatric testimony describing Leopold as emotionally detached and obsessed with intellectual superiority, and Loeb as a pathological liar with fantasies of committing crimes. The defense portrayed the murder as the result of a folie à deux, a shared psychosis between two young men who reinforced each other’s delusions.
The prosecution, led by State’s Attorney Robert Crowe, presented its own psychiatric experts who found both defendants legally sane and fully aware of their actions. Crowe argued that the crime was premeditated, calculated, and carried out by two men who understood right from wrong and chose murder anyway.
Darrow’s closing argument, delivered over 12 hours across two days, became one of the most famous courtroom speeches in American legal history. He argued against the death penalty on moral grounds, emphasized the defendants’ youth, and asked the court to consider whether executing two teenagers would serve justice or merely satisfy public vengeance.
Sentencing and aftermath
On September 10, 1924, Judge Caverly sentenced Nathan Leopold and Richard Loeb to life in prison for murder and 99 years for kidnapping. He cited their age as the primary mitigating factor and stated that the court should not impose the death penalty on minors, even in cases of extraordinary brutality. The decision was met with outrage from much of the public and relief from those who opposed capital punishment.
Leopold and Loeb were transferred to Stateville Penitentiary in Joliet, Illinois. They were housed in separate cellblocks but occasionally crossed paths. In 1936, Richard Loeb was killed in a prison fight by another inmate, James Day, who claimed Loeb had made sexual advances. The circumstances of the attack were disputed, and no charges were filed against Day.
Nathan Leopold remained in prison for 33 years. He earned a degree, taught other inmates, and volunteered for medical experiments during World War II. In 1958, he was granted parole and moved to Puerto Rico, where he worked as a medical technician and married. He published a memoir, “Life Plus 99 Years,” in 1958 and died of a heart attack in 1971.
Unresolved questions and legacy
The murder of Bobby Franks left several questions that were never conclusively answered. The allocation of physical responsibility between Leopold and Loeb remained unclear, as did the full psychological dynamic that led two academically successful young men to commit murder. Psychiatric evaluations produced conflicting conclusions, and neither defendant provided a coherent explanation for why they carried out the crime beyond vague references to thrill-seeking and intellectual superiority.
The case influenced American legal discourse on juvenile sentencing, the role of psychiatric testimony in criminal trials, and the ethics of the death penalty. It also became a cultural touchstone, inspiring novels, plays, and films including Alfred Hitchcock’s “Rope” and the play “Never the Sinner.” The case remains a reference point in discussions of privilege, responsibility, and the limits of psychological explanations for violence.
Bobby Franks’ family largely withdrew from public life after the trial. His father, Jacob Franks, died in 1941. The Franks family home in Kenwood was later demolished. The culvert where Bobby’s body was found is now part of a nature preserve, unmarked and overgrown.
