The Trial Dispute over the Missing Glass and Fingerprint Evidence turns a physical exhibit into the center of a contest over proof, police handling, and procedural fairness. Prosecutors had built part of their case around fingerprints reportedly lifted from a drinking glass at the crime scene, but the glass itself disappeared before trial. The court allowed testimony about those prints despite the defense’s objection, yet the absence of the object remained a visible weakness in the prosecution’s case. Later testimony and Larren Lyttle’s decision to end the trial exposed how little the circumstantial evidence could establish; a still later account by Rusty Sabich connected the glass to Barbara Sabich’s effort to frame him.

The glass as evidence

Before trial, Rusty assessed the case against him as a collection of circumstantial links. Prosecutors listed witnesses including Dan Lipranzer, Mrs. Krapotnik, Raymond Horgan, Tommy Molto, and Painless Kumagai. Their physical and scientific evidence included telephone records showing a call from Rusty’s home to Carolyn Polhemus’s apartment, biological evidence, and fibers matching carpet in Rusty’s home. The glass was especially important because it supposedly bore two of Rusty’s fingerprints, matched against prints he had provided years earlier for his county employment file. None of the listed witnesses, Rusty observed, could testify to seeing him kill Carolyn or to an actual confession.

The prosecution had repeatedly promised the glass would be produced. On the third morning of trial, however, Nico Delia Guardia acknowledged that it could not be found. Larren Lyttle immediately challenged the prosecution’s position: the defense had lacked a chance to examine the exhibit, and the state had referred to it repeatedly in its opening statement. Nico said the police had apparently possessed it last. Lyttle treated that answer as a serious failure, barred further discussion of evidence no one could locate, and left open whether the glass might later be admitted if it were found.

The loss disrupted the prosecution’s planned order of proof. Its first witness was expected to describe the crime scene and mention the glass, so Lyttle’s ruling forced the state to reconsider how to proceed. The next day, Nico described a six-hour, item-by-item search of the police evidence room. Neither side disputed that the glass was missing; instead, their written arguments addressed whether witnesses could still describe fingerprint evidence derived from it.

The ruling and its limits

Alejandro Stern argued that Rusty should not have to confront scientific testimony without being able to inspect the physical object on which it depended. The prosecution replied that the chain of custody had not been challenged: testimony from Harold Greer, Lipranzer, and laboratory supervisor Maurice Dickerman would establish that fingerprint lifts had been taken from the glass the day after the murder. The judge faced a choice that, as Rusty understood it, fell within the permissible bounds of legal judgment either way. Excluding the testimony could devastate the state’s case; admitting it risked allowing the jury to hear conclusions about an exhibit the defense had never examined.

Lyttle admitted the fingerprint testimony over objection. He said the evidence’s importance influenced him, but stressed that the defense’s skepticism was understandable and that the missing object could not be presented. He also pointed to the police evidence room’s history of poor record-keeping and handling of exhibits. Although he did not decide that the prosecutors had acted in bad faith, he warned that proof of such conduct could end the prosecution. He planned a strongly worded limiting instruction for the jury, and Rusty’s wife, Barbara, objected to the ruling as unfair: Rusty had not even had an opportunity to look at the glass.

The instruction did not erase the evidence, but it shaped how the jury could regard it. Lyttle acknowledged the possibility of acquittal and made the case’s evidentiary uncertainty part of the courtroom record. Dickerman then explained fingerprint identification with photographs and slides, including images of the bar, the glass, the lifts, and enlargements from Rusty’s employee file card. Red arrows marked the points of comparison. His polished presentation gave the prosecution a forceful account of the fingerprints, even though the jury could not see or inspect the original glass.

The evidence under pressure

The dispute mattered beyond the missing exhibit itself: the case depended on the combined force of inferences about Rusty’s presence, contact with Carolyn, and the timing and meaning of the scientific evidence. Dickerman’s testimony made the fingerprint comparison concrete, but it could not restore the defense’s lost opportunity to examine the object. Nor did a fingerprint, by itself, establish when it had been left or prove that Rusty had committed murder. The limiting instruction put that gap into view even as the judge allowed the prosecution to proceed.

The prosecution’s biological evidence also came under pressure. During Stern’s cross-examination, he asked Painless Kumagai whether Carolyn was a woman who knew she could not conceive. Kumagai answered no. The exchange became relevant to the larger question of what the scientific evidence could actually establish. In his later explanation to Barbara, Rusty said that Carolyn had in fact undergone a tubal ligation, and that the prosecution had failed to account for it. He also described other traces—the home telephone record, carpet fibers, and a third fingerprint—as consequences of Barbara’s effort to direct suspicion toward him. That retrospective account recasts the apparent accumulation of evidence: details that had seemed to converge on Rusty could instead be understood as traces of a setup, compounded by investigative assumptions and missed clues.

The trial ends

After considering the case, Lyttle concluded that the evidence was inadequate to send the jury into deliberations. He found no proof of motive, no concrete evidence establishing an intimate relationship, and no effective proof that Rusty had had sexual relations with Carolyn on the night she died. He acknowledged that the state might be entitled to infer Rusty had been at the scene, but said the missing glass affected his confidence in the prosecution’s case. In his view, there was no direct proof that Rusty had murdered Carolyn, and the remaining evidence could not fairly support continuing the trial.

Lyttle granted the defense motion, discharged Rusty, and dismissed the case. His decision ended the prosecution without resolving the murder itself: it determined that the evidence presented could not justify continuing against Rusty, not who had killed Carolyn. The missing glass therefore carries two meanings. In court, it marks a failure of evidence custody that weakened the state’s ability to prove its case. In the novel’s later account, it belongs to a wider pattern of planted and misread traces, showing how forensic details can appear persuasive while remaining vulnerable to a different explanation.
