THE ROBISON
FAMILY

In the summer of 1968, the Robisons of Lathrup Village, Michigan represented the pinnacle of mid-century suburban prestige. Their sanctuary was "Summerset." By July, it would be their tomb.

Richard Robison was a cultured advertising executive and publisher of the arts magazine Impresario. His wife Shirley raised four mannerly children in one of Detroit's most affluent enclaves. Their retreat — a five-room log-and-stone cottage tucked at the end of a private drive in the "tunnel of trees" near Good Hart — was called Summerset.

The tranquility fractured on June 23, when 18-year-old Norman Bliss, son of the resort's caretaker, died in a motorcycle accident. On the evening of June 24, Richard Sr. visited the grieving caretaker, Chauncey "Monnie" Bliss, to offer condolences and a twenty-dollar donation for flowers. He mentioned the family would be departing the next day for a multi-week vacation to Kentucky and Florida.

This polite, forgettable interaction was the killer's alibi. When the Robisons vanished, the community assumed they had simply followed through on their southern itinerary. Instead, for 27 days, the family remained inside Summerset — not as vacationers, but as victims.

A Masterclass in Crime Scene Staging

THE 27-DAY
ILLUSION

The duration for which the murders remained hidden was no accident. It was a tactical achievement — a killer's deliberate exploitation of community assumptions, a month-long head start purchased with curtains, cardboard, and a handwritten sign.

After the shootings, the perpetrator engaged in meticulous environmental staging. Curtains drawn. Doors locked. Heating system turned to high. This last detail was a deliberate choice to accelerate decomposition — creating what investigators later called a "wretched condition" that compromised the recovery of physical evidence and fingerprints.

To mask the violence from outside, the killer taped cardboard over a window shattered by initial rifle fire. A note was affixed to the front door in careful block letters:

WILL BE BACK — ROBISON

— Note found on the door of Summerset cottage, July 1968

The staging combined with the family's pre-announced travel plans gave the perpetrator a nearly month-long head start. The family's Ford station wagon and Chrysler Newport sat undisturbed under a thickening layer of dust. No one thought to look.

The Forensic Trail

THE BALLISTIC
FINGERPRINT

The forensic reconstruction at Summerset revealed a specific ballistic signature that led investigators directly to their prime suspect. It was, the Michigan State Police agreed, a blindingly clear trail. The only mystery was why it led nowhere.

The killer used two weapons: a .22-caliber AR-7 ArmaLite rifle — fired through the rear window in the initial assault — and a .25-caliber Beretta pistol, used for the final executions at close range. The most damning evidence was the discovery of rare Finnish SAKO .25-caliber shell casings.

This specific ammunition was sold for only a limited time in Michigan in early 1968. Records showed that Joseph Scolaro III — Richard Robison's business associate — purchased this rare ammo on February 2, 1968, the exact same day he purchased two Beretta pistols. Furthermore, .22-caliber shell casings found at the Union Lake firing range — owned by Scolaro's father-in-law — provided a forensic match to the unique firing-pin impressions at the crime scene.

THE "KEY MAN"
MOTIVE

The Good Hart massacre was not spontaneous violence. It was a white-collar embezzler's violent pivot when the walls began to close in — six lives traded for the chance to outrun a spreadsheet.

Richard Robison Sr. was an exacting man who demanded precision in his business. On the morning of June 25, 1968, he contacted Frank Joity, his banker at the National Bank of Detroit, and discovered that approximately $60,000 had been embezzled from his agency by the man he trusted most.

Throughout that final morning, Robison placed 17 urgent and angry calls to Scolaro at the Southfield office, demanding an explanation. Each unanswered or deflected call tightened the noose. Scolaro was also motivated by a $200,000 "key man" life insurance policy he mistakenly believed was active — in reality, Robison had not yet completed the required physical exam. The policy would pay nothing. Scolaro murdered six people for a policy that did not exist.

$60K Amount embezzled Discovered by Robison on the morning of June 25 via a call to the National Bank of Detroit. The trigger that started the clock.
17 Calls Robison made to Scolaro Urgent, angry, unanswered or deflected. Each call a message: I know. Each call pulling Scolaro closer to the decision he had already half-made.
$200K "Key Man" insurance policy Scolaro believed it was active. It was not — Robison had never completed the required physical. Six people died for a policy that would never pay out.

While Richard Sr. harboured his own enigmas — including a secretive "Superior Table" project and a mysterious benefactor named "Mr. Roberts" — these proved to be narrative red herrings. The financial pressure on Scolaro provided the only motive logical enough to fuel the systematic elimination of an entire family.

When Politics Thwarts Justice

JURISDICTIONAL
PARALYSIS

The Michigan State Police had their man. The ballistics were clear. The motive was documented. And the county prosecutor — a retired attorney who had won the office by write-in vote because nobody else wanted it — declined to prosecute.

Donald Noggle, Emmet County prosecutor, cited the lack of fingerprints as his reason to avoid trial. The decomposition that had destroyed the fingerprint evidence had, of course, been engineered by the killer. The staging that made prosecution difficult was itself evidence of premeditation.

The Emmet County Board of Commissioners compounded the failure. "Frugal to a fault," they refused to fund a trial that promised to be long, expensive, and logistically grueling. They viewed the tragedy as a "downstate matter" — involving Detroit-area people — and argued that local property taxes should not be used to resolve a conflict from the suburbs of Southfield.

No fingerprints — Destroyed by biological decomposition — itself engineered by the killer's deliberate use of the heating system

Financial objection — County "frugal to a fault" — Board of Commissioners refused to fund a lengthy trial

Political cover — Prosecutor Noggle a retired attorney, write-in winner, conservative — maximum aversion to risk

Jurisdictional deflection — Case labelled a "downstate matter" — Southfield victims in an Emmet County crime scene

Result — Zero prosecutions. The ballistic fingerprint went nowhere. The killer walked free for five years.

The Suicide Note Paradox

I AM A LIAR...
BUT NOT A MURDERER

The case reached its tragic, if predictable, finale in 1973. When Joseph Scolaro III learned that Oakland County prosecutors were finally bypassing the Emmet County impasse to charge him with conspiracy to commit murder, he made his final choice.

On March 8, 1973, Scolaro was found dead in his chair. He had shot himself with a Beretta pistol. For five years, he had driven past Acacia Park Cemetery — where the Robison family was buried — on his daily commute to work.

His suicide note presented a chilling paradox. It began with a candid admission that he was a "liar-cheat-phony" and a forger. Having established this comprehensive record of dishonesty, his final words were:

"P.S. I had nothing to do with the Robisons — I'm a cheat but not a murderer."

— Postscript to the suicide note of Joseph Scolaro III · March 8, 1973

To investigators, the logic was flawed by design. If the note begins with a comprehensive confession of chronic lying and deception, the postscript denying murder carries no weight at all. It was seen as a final, desperate attempt to shield his own family from the stigma of mass murder — a last performance by a man who had been performing for five years.

The suicide weapon — a Beretta pistol — matched the type used at Summerset. Whether this was coincidence, irony, or a last private confession visible only in retrospect, no one alive can say.

Epilogue · The Legacy of Summerset

The Empty Lot at Purgatory Bay

The Good Hart murders remain officially open under Michigan law. Yet for the detectives who spent years on the trail, it has long been considered solved. The only mystery was the refusal of the system to say so out loud.— this research series

The Good Hart murders remain officially open under Michigan law. Yet for the detectives who spent years on the trail, it has long been considered solved. The only mystery was the refusal of the system to say so out loud — the peculiar silence of a county that knew what it knew and chose to know it privately.

The physical site of the tragedy was erased shortly after the investigation. The Summerset cottage was demolished and burned in 1969 — the biological saturation of the logs made the structure uninhabitable. Today the property is a vacant waterfront lot at Purgatory Bay: a quiet, unintentional memorial.

A single artifact remains: the Summerset sign that once hung over the fireplace, now residing in the Michigan Room of the Petoskey Public Library. It is the only physical remnant of six lives that ended there in the summer of 1968, and of the five years during which their killer drove past their graves on his way to the office.

When the legal system fails and a suspect chooses his own ending, can there ever be true justice — or does the truth remain forever buried in the sand of Purgatory Bay?

Joseph Scolaro III — dead 1973. Summerset cottage — demolished 1969. Case status — officially open.
