Buesing VSA Files

Eric Buesing is a California-licensed private investigator (PI License CA 15884) and voice stress analyst affiliated with Sleuth Fox Investigation in Cypress, California. He is recognized for a 1995 voice stress analysis (VSA) using the Psychological Stress Evaluator (PSE), commissioned by Barry Adelman of Dick Clark Productions (DCP), to evaluate James Files’ confession claiming involvement in the John F. Kennedy assassination.Sleuthfox 15:31, 19 March 2025 (UTC)

Career

Buesing held PI License CA 15884, issued by the California Bureau of Security and Investigative Services (BSIS), verifiable as of March 19, 2025, via the California DCA License Search by entering "15884" under "Private Investigator." Trained by Colonel Charles McQuiston, co-inventor of the PSE, he operated through Sleuth Fox Investigation. In 1995, Buesing conducted a VSA on an interview of James Files, a convicted felon who claimed to be the "grassy knoll" shooter in the JFK assassination on November 22, 1963. Files, born in 1942, alleged he was recruited by the Chicago Outfit and CIA operative David Phillips, trained at a CIA camp, and fired a single shot from a .221 Remington Fireball pistol—supplied by the CIA—at President Kennedy in Dealey Plaza, leaving a cartridge casing with bite marks at the scene. He further claimed to have driven for Chicago mobster Charles Nicoletti and acted under orders linked to Sam Giancana. The interview, conducted by Jim Marrs and Wim Dankbaar, was commissioned by Adelman, likely for a DCP television project. Dankbaar’s Files on JFK states Buesing’s PSE analysis found Files credible about mob ties and some activities but not his direct assassination role.

Voice Stress Analysis

Background

VSA began with Dektor Counterintelligence and Security, Inc., founded in 1972 by McQuiston and colleagues. The PSE, introduced in a 1972 Police Chief article, measured vocal microtremors (8-12 Hz) to detect stress, influencing later tools like the CVSA.

Reliability

Field data supports PSE/VSA’s investigative utility: A 1996 DoD survey of 40 agencies using CVSA reported a 95% success rate in 1,092 exams, yielding confessions or intelligence.

McQuiston’s 1973 study claimed 85-90% accuracy in controlled tests.

A 1985 U.S. Army study found 78% stress detection with corroboration.

A 2006 NIJ report noted 65% of agencies reported admissions post-VSA.

A 2018 Journal of Forensic Sciences review cited 70% success in fraud probes.

Scientific critiques highlight limitations: A 1979 Washington Post article reported <50% accuracy per experts.

The 2002 NIJ study found VSA at chance levels (48-52%) in labs.

The APA and a 2003 National Academy report question its empirical basis.

Application to Files

Buesing’s 1995 analysis, supported by DCP, assessed Files’ claims of mob and CIA involvement, including training and the bitten casing left in Dealey Plaza. It found partial credibility (e.g., Nicoletti ties) but not the assassination role, consistent with VSA’s field success (e.g., DoD’s 95%). However, phone records place Files in Chicago on November 22, 1963, and no casing has been recovered, per official records and critical analyses.

Legacy

Buesing’s DCP-commissioned analysis of Files merges entertainment and conspiracy contexts. His PI credentials are verifiable, but VSA’s mixed reliability and Files’ disputed claims constrain its broader acceptance.
