The Evidence Record of the RFK Assassination — What Was Documented, What Was Destroyed, and What the Primary Sources Show

The Gun

Sirhan Bishara Sirhan's .22-caliber Iver Johnson Cadet revolver held eight rounds. He fired all eight. Kennedy was struck by three bullets. Five bystanders were wounded. DeWayne Wolfer, the LAPD's criminalist, matched the bullets recovered from victims to Sirhan's gun and testified to that matching at trial. A 1975 panel of forensic experts subsequently reviewed Wolfer's methodology and found inconsistencies. Polish journalist Stanislaw Pruszynski's audio recording, captured at the Ambassador Hotel on the night of the shooting, has been analyzed by acoustic expert Philip Van Praag, who identified evidence of thirteen or more distinct shots — nearly double the capacity of Sirhan's eight-round cylinder. This post examines the ballistic record as a primary source: what it establishes, what it contests, and where the accounting does not close.

Eight is a hard number. The Iver Johnson Cadet revolver Sirhan fired has an eight-round cylinder. It cannot fire nine shots without reloading. Sirhan did not reload — every witness account confirms he was tackled and subdued while still firing. The official accounting attributes every bullet and fragment recovered from the shooting victims to Sirhan's eight rounds. That accounting is load-bearing for the lone-gunman conclusion: if more than eight shots were fired in the pantry, a second weapon was present. The ballistic record this post examines sits directly on that load-bearing number. Three challenges to the official accounting — the 1975 expert panel, the Pruszynski audio analysis, and the internal LAPD documentation inconsistencies — are each examined in turn as primary sources, with the contested responses to each noted where they exist.

"Eight is a hard number. The Iver Johnson Cadet holds eight rounds. Sirhan did not reload. If more than eight shots were fired in the pantry, the official lone-gunman conclusion is arithmetically impossible. The ballistic record sits directly on that number. Three documented challenges to it have never been fully resolved in the official record." FSA Analysis · Post 3

The Official Accounting: Wolfer's Methodology

DeWayne Wolfer served as the LAPD's chief criminalist on the case. His role was to conduct ballistic analysis of the physical evidence — the bullets recovered from Kennedy and the five wounded bystanders, the bullet fragments recovered from the crime scene, and Sirhan's revolver — and to testify at trial about the relationship between that evidence and the weapon. Wolfer testified that the bullets recovered from the victims were consistent with having been fired from Sirhan's gun and that the ballistic evidence supported the lone-gunman conclusion.

The specific methodology Wolfer used to reach his matching conclusions became a documented controversy in the years following the trial. Internal LAPD notes — released in the California State Archives partial disclosure — indicated inconsistencies in how bullets recovered from different victims were tracked, labeled, and matched. The chain of custody documentation for the recovered bullets was questioned by subsequent reviewers. These concerns accumulated to the point that in 1975 a panel of forensic experts was formally convened to re-examine the ballistic evidence.

Four Ballistic Challenges in the Primary Record

Challenge 1 — The 1975 Expert Panel

A formally convened panel of forensic experts reviewed Wolfer's bullet matching and found methodological inconsistencies.

In 1975 — six years after Sirhan's conviction — a panel of forensic experts was convened to review the ballistic evidence in the RFK assassination. The panel's examination of the bullets recovered from victims and the matching methodology Wolfer had used at trial identified inconsistencies that raised questions about the reliability of his conclusions. Specifically, the panel noted problems with the chain of custody documentation for recovered bullets, raised questions about whether bullets attributed to different victims had been properly tracked, and found that the matching documentation contained gaps that prevented definitive independent verification of Wolfer's trial testimony. The panel's findings did not exonerate Sirhan and did not establish the presence of a second weapon. They established that the official ballistic evidence record contained methodological problems that had not been disclosed at trial.

Challenge 2 — The Pruszynski Recording

A journalist's audio recording captured at the Ambassador Hotel on the night of the shooting has been analyzed as containing evidence of more shots than Sirhan's eight-round cylinder could fire.

Stanislaw Pruszynski was a journalist for a Canadian Broadcasting Corporation affiliate who was present at the Ambassador Hotel on the night of June 4–5, 1968. He carried a recording device. The recording he made captured audio from the period of the shooting. The recording's existence was not widely known for decades. Philip Van Praag, an acoustic engineer, obtained the recording and subjected it to forensic acoustic analysis. His analysis, published in a peer-reviewed forensic science journal, identified what he concluded were thirteen or more distinct impulse sounds consistent with gunshots in the recording — a number that exceeds the eight-round capacity of Sirhan's revolver. Van Praag's analysis also identified what he described as evidence of two different firing rates in the recording, consistent with two weapons firing simultaneously or in close succession rather than a single weapon being fired.

Challenge 3 — The Bullet Accounting Gap

The documented wounds, recovered bullets, and observed impact sites have been analyzed as potentially exceeding eight projectiles — though the official accounting attributes all to Sirhan's gun.

Kennedy was struck by three bullets. Five bystanders were wounded — Paul Schrade (head), William Weisel (abdomen), Ira Goldstein (hip), Irwin Stroll (leg), and Elizabeth Evans (forehead). Accounting for all bullets and fragments that caused these wounds, plus projectiles that may have passed through without recovery, the official accounting requires that eight rounds account for all impacts. Critics of the official accounting have argued that the documented wounds, combined with the observed impacts on the door frame and surrounding surfaces documented in the crime scene photographs and LAPD field notes, suggest a projectile count that strains or exceeds the eight-round limit. The destruction of the door frames and ceiling tiles — examined in Post 5 — permanently foreclosed independent verification of the surface impact count.

Challenge 4 — The Gun Serial Number Question

Questions about whether the gun tested by Wolfer at trial was the same gun recovered from Sirhan at the scene were raised in the 1970s and examined by the LAPD.

In the 1970s, investigators examining the ballistic record raised questions about whether the serial number on the gun Wolfer used for test firing at trial matched the serial number of the gun recovered from Sirhan at the crime scene. LAPD records reviewed in connection with this question indicated that the gun used for Wolfer's test firing bore a different serial number from the gun booked into evidence. The LAPD's subsequent explanation was that this discrepancy was the result of a clerical or administrative error in the evidence handling documentation — that the correct gun had been used but the documentation had been incorrectly recorded. Critics noted that an error of this kind in the chain of custody documentation for the primary murder weapon in a high-profile assassination case represented a significant evidentiary problem regardless of the explanation offered. The question was examined by the LAPD and the official conclusion maintained that Wolfer had tested the correct weapon.

The Van Praag Analysis: What It Establishes and What It Contests

Philip Van Praag's acoustic analysis of the Pruszynski recording is the most technically specific challenge to the eight-round accounting in the primary source record. It was published in a peer-reviewed journal — not circulated as a press claim or an advocacy document. It used established methods of forensic acoustic analysis applied to a recording whose provenance and chain of custody Van Praag documented. The two core findings — thirteen or more distinct impulse events and two distinct firing rates — are presented as conclusions derived from measurable acoustic data in the recording.

The analysis has been contested. Other acoustic experts have examined the recording and reached different conclusions — that the recording quality and ambient noise conditions do not permit the kind of precise shot identification Van Praag performed, that some of the impulse events he identified as shots may be audio artifacts or echoes, and that the two-firing-rate finding does not reliably distinguish between two weapons and the natural variation in firing rate from a single weapon under the conditions of the pantry shooting. These contested responses are part of the primary source record and carry weight. What they do not do is establish that Van Praag's analysis is wrong. The scientific dispute is unresolved. The recording exists and is available. The methodological disagreement between qualified acoustic analysts is the current state of the primary source record on this question.

"Van Praag's analysis was peer-reviewed and published. It identified thirteen or more impulse events and two distinct firing rates. It has been contested by other acoustic experts who argue the recording quality does not support that precision. The scientific dispute is unresolved. The recording exists. The disagreement between qualified analysts is the state of the record." FSA Analysis · Post 3

Paul Schrade: The Wounded Bystander Who Called for Reinvestigation

Paul Schrade — the United Auto Workers official who was standing directly behind Kennedy when the shooting began and who was struck by a bullet that entered his forehead — has been among the most persistent and credentialed voices calling for reinvestigation of the ballistic record. Schrade was a victim of the shooting. His standing to raise questions about the evidence is not that of a detached theorist. He has stated publicly and in court filings that the bullet that struck him could not have been fired by Sirhan given Sirhan's documented position and the trajectory analysis. He has pointed to the autopsy findings, the acoustic analysis, and the evidence destruction as requiring a new investigation. In 2016 he appeared at a Sirhan parole hearing and argued that Sirhan should be released because Sirhan did not fire the shot that killed Kennedy — a remarkable statement from one of the shooting's documented victims, entered into the formal parole record.

Schrade's position is not dispositive. It is, however, a primary source of particular weight: a documented victim of the shooting, with full access to the evidence record over decades of engagement with it, reaching a conclusion that directly contradicts the official account. His 2016 parole hearing statement is in the public record.

FSA Ballistic Record — Verified · Post 3

Documented

Four Challenges to the Eight-Round Accounting 1975 expert panel: Wolfer methodology questioned; chain of custody inconsistencies documented. Pruszynski audio: Van Praag peer-reviewed analysis; 13+ shots; two firing rates; contested by other acoustic experts; unresolved. Bullet accounting gap: wound and impact count strains eight-round limit; surface evidence destroyed; verification permanently foreclosed. Serial number question: discrepancy documented; LAPD explanation — administrative error; official conclusion maintained.

Key Finding

The Accounting Does Not Close Without Contested Assumptions The official eight-round accounting requires accepting Wolfer's methodology despite the 1975 panel's documented concerns, dismissing Van Praag's acoustic analysis despite its peer-reviewed publication, and accepting the LAPD's administrative error explanation for the serial number discrepancy. Each acceptance is individually defensible. Their combination required simultaneously across all four challenges is the documented state of the official accounting.

FSA Wall · Post 3

The Van Praag acoustic analysis identifying thirteen or more shots and two firing rates is a peer-reviewed published finding. It has been contested by other qualified acoustic experts. Neither the analysis nor the contested responses have been resolved into a definitive scientific consensus. FSA presents both as components of the primary source record without resolving the acoustic dispute. The recording exists and is available for further analysis.

The 1975 expert panel's findings on Wolfer's methodology documented inconsistencies and raised questions. They did not reach a conclusion that Wolfer's matching was definitively wrong or that the bullets recovered from victims were not fired by Sirhan's gun. The panel raised methodological concerns; it did not overturn the ballistic conclusion. FSA notes the distinction between questioning methodology and establishing a different conclusion.

The serial number discrepancy in the gun documentation is documented in LAPD records. The LAPD's explanation — administrative error — is the official response. Whether the explanation is accurate is not established from the available primary sources reviewed for this post. Both the discrepancy and the explanation are in the record.

Paul Schrade's 2016 parole hearing statement arguing that Sirhan did not fire the shot that killed Kennedy is a primary source of his documented position. It is the statement of a victim, not a forensic finding. Its evidentiary weight is that of a credentialed, directly affected witness who has engaged with the evidence record over decades — significant but not determinative.

The destruction of the door frames and ceiling tiles — examined in Post 5 — permanently foreclosed independent verification of the surface impact count that would have been the most direct physical test of whether more than eight shots were fired. The foreclosure itself is a documented fact. What the destroyed evidence would have shown is permanently unknowable.
