Overview of The Boat Ramp (Park Predators — Audiochuck)
This episode, hosted by Delia D’Ambra, recounts the unsolved “Kingfish boat ramp” murders that occurred on Anna Maria Island, Florida on August 1, 1980. It follows the facts, witness accounts, investigative efforts, suspects and theories surrounding a violent daylight attack that left three members of the Dumois family and a neighbor dead, and another man critically wounded. The episode emphasizes the human impact, forensic and investigative challenges, and why the case remains cold decades later.
Key takeaways
- On August 1, 1980, a man posing as an injured bicyclist was taken into a family station wagon at the Kingfish boat ramp. The assailant shot four people in the vehicle—killing three—and later shot and killed a nearby neighbor who confronted him at a grocery-store parking lot.
- Victims: Juan Dumois (46, pediatrician), Eric Dumois (13), Mark Dumois (9) — all killed; Robert Matzke (60, neighbor/retired Lt. Col.) — killed at Foodway parking lot; Raymond Barrows (52) — shot in neck and survived.
- The killer was described by witnesses as a slender white male (30–40s) with wavy dark hair, wearing white shorts/shirt, who fled on a bicycle and then left in a waiting car. A composite sketch(s) was released, but sketches varied over time.
- Investigative problems—crime-scene contamination, delayed public alerting, inconsistent witness accounts, lack of surveillance, lost/unclear forensic opportunities—hampered identification and arrest.
- Several leads and suspects were pursued (including Richard Lee Whitley and mob-related tips), but none were proven. Vital physical evidence (a bullet from Raymond) was preserved; prints were collected but never matched publicly. The murders remain unsolved.
Timeline of events
- August 1, 1980 (shortly before 5:00 p.m.): Dumois family loads boat at Kingfish ramp. A young relative Annie and cousin Anna pass by; later the family leaves the ramp with a bicyclist in the backseat.
- Minutes later on Manatee Avenue: the station wagon and boat trailer jackknife; first responders find Juan and two boys shot dead in the car and Raymond critically wounded on the ground.
- Simultaneously at Foodway grocery parking lot: neighbor Robert Matzke is found shot in the head in his car after confronting the same suspect; assailant flees in a waiting vehicle.
- Subsequent investigation: fingerprints and evidence collected, composite sketches made (multiple versions), $10,000 reward approved, leads pursued (including Richard Whitley—later cleared), media coverage and county/federal involvement. Raymond dies of a heart attack in May 1982; bullet removed at autopsy turned over to FDLE.
Victims, witnesses & survivor account
- Survivors/witnesses: Raymond Barrows (survived but later died in 1982); Annie Barrows (his daughter) provides much of the family perspective in the episode.
- Raymond’s account (hospital interview): hitchhiker asked for a ride, put a bicycle in the boat, sat in the back between the boys; during travel the shooter displayed a .22 and shot occupants in quick succession. Raymond lost consciousness and later woke on the grass.
- Sketches were produced from Raymond’s recollections and other witness statements; subsequent hypnosis sessions and later sketches produced inconsistent results.
Investigation: evidence collected and problems
- Evidence gathered: latent fingerprints from the Dumois station wagon and Matzke’s car; bullet fragments; preserved full-caliber bullet recovered later from Raymond at autopsy (1982); fiber samples vacuumed from the station wagon.
- Not found or inadequate: murder weapon not recovered; crime-scene preservation compromised by bystanders and first responders; initial delay publishing an all-points bulletin and bridges were not closed—possible escape route left open; grocery store surveillance either absent or not relevant; some fingerprint opportunities (children’s prints) were not taken before burial.
- Photos taken by a passerby captured the suspect walking away but were out of focus due to camera settings.
- Fingerprint matches and DNA links were not publicly reported; prints collected were never positively identified to a suspect.
Suspects, leads and theories
- Richard Lee Whitley: early suspect based on a community tip; had violent criminal history and was wanted for murder in Virginia. He had an alibi (seen and signed into a mission in Tampa at ~5:05 p.m.) and his prints did not match; he was cleared for the boat-ramp murders.
- Mafia/hit-squad hypothesis: explored intermittently (including claims made by imprisoned mobster Donald Frankos, who alleged the murders involved a contract killing and a mistaken target). Investigators could not substantiate Frankos’ claims and leads tied to his statements did not yield arrests.
- Theories remain divided:
- Professional hit: some investigators noted the ruse, apparent getaway plan, and small-caliber firearm as possible signs.
- Random or mentally disturbed attacker: others argued the brazen daylight shooting in front of witnesses and other odd details suggested a non-professional, impulsive killer.
- Mistaken identity: family members (notably Annie) believe the killer may have intended someone else—i.e., a planned hit on a different target that tragically struck this family instead.
Aftermath and impact
- Families endured long-term grief and uncertainty: funerals drew community support; families tried to move on while pressing for answers.
- Investigative attention ebbed and flowed over decades: anniversaries prompted renewed reporting; new media treatments (2019 local coverage, 2022 Down and Away podcast, 2025 book) revisited the case but no arrest followed.
- Structural lessons: the case is frequently cited as an example of how early scene contamination, delayed alerts, and lost forensic opportunities can derail homicide investigations.
Notable quotes and details
- Witnessed outcry from Raymond: police report he heard Juan yell, “Why did you shoot them?”
- One investigator: “I lean toward the bizarre. I don't think there was any Machiavellian intent in this. It was probably a crazy person who just did it on the spur of the moment.”
- Law enforcement criticism: delayed bulletin release (~40 minutes after murders in some reports) and inability to seal bridges were controversial points.
Where the case stands and how listeners can help
- Status: Unsolved as of this episode; evidence (including the bullet removed at autopsy) is reportedly in FDLE custody and some physical evidence still exists in department evidence rooms.
