In the early 1920s, a dramatic feud unfolded in eastern Kentucky that captured the attention of newspapers across the state. What began as a deadly confrontation on the streets of Olive Hill soon spiraled into allegations of revenge, a hired assassin, courtroom drama, and years of legal battles. The story of the Biggs–Duvall case remains one of the most remarkable criminal episodes in Carter County history.
A Killing in Olive Hill
The saga began in November 1921 in the small town of Olive Hill, Kentucky. Dr. Harvey L. Biggs, a well-known physician who had previously practiced in Ashland, was shot and killed on a street corner. The man accused of the killing was Charles F. Duvall, a local resident who worked as a troubleshooter for the telephone company.
The shooting shocked the community. According to reports from the time, Duvall claimed that Dr. Biggs had confronted him over allegations involving Duvall’s daughter. Words were exchanged, and in the course of the confrontation Duvall shot the physician.
When the case went to trial in Carter County, a jury acquitted Duvall after hearing the testimony. The verdict left the Biggs family devastated and angered. To many observers, the acquittal seemed to close the legal chapter of the killing. In reality, it was only the beginning.
The Alleged Revenge Plot
In the months following the acquittal, authorities began investigating what they believed was a plot to retaliate against Duvall.
The prosecution later alleged that members of the Biggs family—Jack Biggs, Bob Biggs, their sister Maude Biggs, and their nephew Cam Biggs—had entered into a conspiracy to have Duvall killed.
The alleged assassin was Dominique Giardiana, an Italian immigrant from Marion, Ohio who operated a soft drink and spaghetti stand in Gary, Indiana.
According to Giardiana’s later testimony, members of the Biggs family approached him in Indiana with a contract killing proposal. The arrangement, he claimed, was straightforward:
-
$50,000 if Duvall was killed
-
$25,000 if the attempt failed but wounded him
One account reported that a $100 bill was thrown on the table during the meeting to cover travel expenses.
Whether the story was true or fabricated would become the central question in the trials that followed.
An Ambush in the Mountains
In June 1922, the alleged plan was set into motion.
Telephone wires along the Midland Trail near Barrett’s Creek, not far from the Biggs property, were deliberately cut. Because Duvall worked as a repairman for the American Telephone and Telegraph Company, the conspirators allegedly expected he would be sent to repair the damage.
Their prediction proved correct.
Duvall arrived at the scene with companions to repair the line. As they worked along the remote stretch of road, gunfire erupted from ambush.
Shots were fired at the repair crew, but the attackers failed to kill their intended target. Duvall survived the assault.
The gunmen fled.
Authorities quickly began searching the area.
The Arrest of Dominique Giardiana
The day after the shooting, law enforcement officers tracked down Dominique Giardiana near Grayson.
According to accounts given later in court, he had spent the night hiding in a coal bank after the attack and attempted to reach the railroad in hopes of escaping the region.
Instead, he was arrested and brought before the court.
Giardiana was charged with the ambush of Duvall and eventually convicted. He was sentenced to eight years in the Kentucky State penitentiary.
But the story did not end with his conviction.
Before long, Giardiana claimed that he had not acted alone.
The Biggs Family Indicted
Giardiana told investigators that he had been hired by members of the Biggs family to carry out the attack. His confession led to a dramatic development in the case.
A Carter County grand jury indicted four members of the Biggs family:
-
Jack Biggs
-
Bob Biggs
-
Maude Biggs
-
Cam Biggs
They were charged with conspiracy to murder Charles F. Duvall.
Because the case had stirred intense public feeling in Carter County, the defense requested a change of venue. The trial was moved to Lawrence County Circuit Court in Louisa, where a jury would hear the case.
The Sensational Trial
The trial of Jack Biggs, the first defendant to face the charges, quickly became one of the most closely watched criminal cases in eastern Kentucky.
The prosecution’s key witness was Dominique Giardiana, who was brought from the penitentiary to testify.
Taking the stand in his prison uniform, he told the jury a dramatic story about the alleged conspiracy. He described the meeting in Gary, Indiana, where the killing was supposedly arranged, and detailed how the ambush was planned.
According to Giardiana, the conspirators expected Duvall to appear after the telephone line was cut. Once he arrived, the attackers would shoot him and flee.
The defense attacked the credibility of the witness, arguing that the entire story was invented by a convicted criminal attempting to shift blame.
Jack Biggs took the stand and denied every accusation.
He admitted that he deeply resented Duvall for the death of his brother but insisted he had never hired anyone to kill him.
After three days of testimony, the jury deliberated.
Their verdict came quickly.
A Conviction
The Lawrence County jury found Jack Biggs guilty of conspiracy in the ambush attempt.
His sentence: eight years in the state penitentiary—the same punishment that had been given to Giardiana.
The verdict stunned many observers in the courtroom. Biggs appeared shocked as the decision was read.
But the legal battle was far from over.
The Appeal
Biggs’ attorneys immediately appealed the conviction to the Kentucky Court of Appeals, the state’s highest court at the time.
The appellate court carefully reviewed the proceedings and ultimately found serious problems with the trial.
In December 1922, the court issued a ruling overturning the conviction.
The justices concluded that erroneous instructions had been given to the jury, making the verdict legally unsound. As a result, the conviction was reversed and a new trial was ordered.
The decision represented a major victory for the defense.
The Final Trial
Several years later, the case returned to the courtroom.
This time Jack Biggs and his sister Maude Biggs stood trial together for their alleged role in the ambush of Charles Duvall.
By then, the prosecution’s case had weakened significantly.
The evidence against the defendants had largely depended on the testimony of Dominique Giardiana. Without that testimony—and after years had passed since the original events—the case was far more difficult to prove.
When the jury heard the evidence, their deliberations were brief.
In January 1926, the jury returned a verdict of not guilty.
Jack and Maude Biggs walked free.
A Case Remembered
Though the legal battle ended in acquittal, the case left a lasting impression on Kentucky legal history.
Years later, in 1946, newspapers still referred to the Duvall–Biggs case as one of the most dramatic trials of the era.
It was also remembered because the prosecutor involved—Fred M. Vinson—would go on to achieve national prominence, eventually becoming Chief Justice of the United States Supreme Court.
The Legacy of the Biggs–Duvall Feud
Looking back, the case reads like a classic Appalachian crime story.
It involved:
-
A street killing in a small town
-
Allegations of family revenge
-
A supposed contract killer from out of state
-
A mountain ambush
-
A sensational trial followed by an appeal
-
And, finally, an acquittal years later.
Yet despite the extensive coverage the case received in newspapers across Kentucky, many questions remain unanswered.
Did the Biggs family truly attempt to avenge the death of their brother?
Or did a convicted gunman fabricate a story to shift blame?
More than a century later, the truth may never be fully known.
What remains certain is that the Biggs–Duvall case stands as one of the most fascinating—and mysterious—criminal episodes in the history of Carter County, Kentucky.
As a side note: Charles Duvall's son Vernon was shot and killed by a deputy jailer while attempting a jail break on January 11, 1925.
