Overview of The Quarry

This episode of Park Predators tells the century-old story of a fatal shooting at what is now Quarry Lake in Harrington Beach State Park, Wisconsin. What began as a claimed hunting accident between two former co-workers, Dominic Manna and August Falcinelli, turned into a murder case marked by disputed ballistics, allegations of jealousy, and later claims of wrongful conviction and racial prejudice. The episode explores how a quiet industrial site became the setting for a crime that still sparks debate over intent, evidence, and justice.

What Happened in 1920

The setting

  • The incident took place near Belgium, Wisconsin, on land formerly owned by the Lakeshore Stone Company.
  • The quarry had produced limestone using dynamite before closing due to changing market conditions.
  • Many former quarry workers, including immigrant laborers, still lived and worked in the area.

The shooting

  • On February 6, 1920, Dominic Manna was walking near railroad tracks after hunting birds.
  • He claimed he tripped, his double-barrel shotgun discharged, and accidentally shot August Falcinelli.
  • Manna immediately sought help and reported the incident to authorities himself.

Why investigators became suspicious

  • The victim’s injuries did not match Manna’s initial description.
  • The coroner found that Falcinelli had been shot twice, not once:
    • one wound to the left hip
    • one fatal wound near the right neck/shoulder area
  • The wounds suggested two shots fired from different distances and angles, which weakened Manna’s accident explanation.

Trial and Conviction

Prosecutors’ theory

  • The state argued that Manna had a motive: jealousy over Falcinelli’s wife.
  • Witness testimony suggested Manna had spent time with Falcinelli’s wife and may have been romantically interested in her.
  • Prosecutors leaned heavily on circumstantial evidence and the physical evidence from the shooting scene.

Defense arguments

  • The defense maintained the death was an accident.
  • They challenged key witness Ferdinand Volt, noting he had been drinking when he made incriminating comments.
  • They also tried to introduce more testimony about Falcinelli’s wife, but some of it was excluded.

Verdict

  • Manna was convicted of first-degree murder in November 1920.
  • His request for a new trial was denied in 1921.
  • He was sentenced to life in prison.

Appeals, Pardons, and Release

Continued legal fight

  • Manna appealed to the Wisconsin Supreme Court in 1923, but the conviction was upheld.
  • He later sought pardons multiple times:
    • denied in 1925
    • denied again in 1929
    • finally successful in 1931

Release and later life

  • His sentence was commuted to 18 years, making him eligible for release.
  • After prison, he worked for the Baltimore and Ohio Railroad.
  • He later married, retired to Florida, and died in 1966.

Bigger Questions Raised by the Case

Was it murder or an accident?

  • The episode stresses that the motive was never definitively proven.
  • Ballistics and wound placement made the accident theory hard to accept.
  • Still, the case relied heavily on circumstantial evidence, leaving room for doubt.

Claims of prejudice

  • Manna alleged he was treated unfairly because he was Italian.
  • A later law review article suggested racial prejudice may have contributed to the conviction.
  • The episode notes that while ethnic tensions existed in the community, direct proof of explicit bias in the prosecution is limited.

Lasting Legacy

  • Today, a historical marker near the Stonehaven Trail in Harrington Beach State Park commemorates the case.
  • The marker presents the killing as motivated by love for Falcinelli’s wife, but the episode emphasizes that this was never proven.
  • The quarry itself has since filled with water and become Quarry Lake, leaving little visible trace of its industrial past.
  • The story endures as a reminder of how quickly a peaceful landscape can conceal a tragic and contested history.

Key Takeaways

  • A claimed accidental shooting became a first-degree murder conviction.
  • Forensic details, especially the two gunshot wounds, were central to the case.
  • Dominic Manna spent more than a decade fighting his conviction.
  • The true motive remains uncertain, and the case continues to raise questions about bias, evidence, and justice.
