Tracy Petrocelli: The Tri-State Killer
Overview
Over a violent six-month period between October 1981 and March 1982, Tracy Petrocelli carved a path of murder across three western states, leaving a trail of stolen vehicles and shattered lives. He killed three people in Washington, California, and Nevada, and is suspected in at least one other disappearance. His known victims were his young girlfriend, a man traveling through the desert, and a car salesman. Petrocelli, who also used the alias John Sylvester Maida, was a drifter and gambler who killed to facilitate his flight from the law. Captured in 1982, he would be convicted of murder in all three states. His case in Nevada became a legal saga, with a death sentence being imposed, overturned, reinstated, and overturned again over several decades, making his name a fixture in state criminal procedure.
Early Life and Background
Tracy Petrocelli was born in 1951 or 1952. Little is publicly known about his upbringing and early life. Before his murder spree, he had a criminal record that included a conviction for kidnapping. In May 1981, just five months before his first known murder, Petrocelli pleaded guilty to kidnapping his 18-year-old girlfriend, Melanie Barker. The couple had a tumultuous two-year relationship, reportedly strained by Petrocelli's gambling addiction. After they broke up, he abducted Barker and forced her on a three-day drive before he was arrested. He received a suspended sentence and was ordered into a drug treatment program. However, he absconded from the rehabilitation center twice, the second time setting the stage for his deadly cross-country journey.
The Murder of Melanie Barker
On October 25, 1981, Petrocelli confronted 18-year-old Melanie Barker outside the Seattle, Washington, restaurant where she worked as a waitress. Witnesses saw Barker running back toward her workplace as Petrocelli pursued her. He then shot her three times in the head and fled the state. Fingerprints left at the scene identified Petrocelli as the killer. He had been out of custody for only a short time after escaping the court-ordered treatment program. The murder of his former girlfriend marked the beginning of his run from the law and his multi-state killing spree.
The Murder of Dennis Gibson
After killing Melanie Barker, Petrocelli fled to California. On November 19, 1981, he encountered 30-year-old Dennis Gibson near Calico, a ghost town in the Mojave Desert. Gibson's body was later discovered by hikers in the rugged terrain of Odessa Canyon. He had been shot and bludgeoned to death. At the scene, investigators found .22 caliber cartridge casings. For years, Gibson's murder remained a cold case. He had told his sister he was planning to tour the West Coast and surf in Baja, California, before his family lost contact with him. The case broke decades later when ballistics tests connected the casings to the .22-caliber Ruger pistol used in Petrocelli's other murders. When Petrocelli was arrested in 1982, he was found in possession of Gibson's birth certificate and driver's license.
The Murder of James Wilson
From California, Petrocelli continued his flight, passing through Oklahoma before arriving in Reno, Nevada. By March 1982, he decided he needed a four-wheel-drive truck. He went to a used car dealership where he met 63-year-old James Wilson. Wilson agreed to let Petrocelli test drive a Volkswagen pickup truck. During the drive, Petrocelli shot Wilson three times with the same .22 caliber pistol used in the previous murders. One shot was to the back of the head from close range. He then buried Wilson's body in a shallow, makeshift grave near Pyramid Lake, covering it with rocks and brush. Wilson's wallet was missing, and his pockets were turned inside out. His son later told authorities that his father, who distrusted banks, often carried large amounts of cash. Petrocelli was arrested in Las Vegas the following month.
The Victims
- Melanie Barker, 18 — October 25, 1981, in Seattle, Washington. An 18-year-old waitress, she was tragically killed by her ex-boyfriend after enduring a prior kidnapping by him.
- Dennis Gibson, 30 — November 19, 1981, near Calico, California. A man with plans to travel the West Coast, his life was cut short while he was journeying through the desert.
- James Wilson, 63 — March 1982, in Reno, Nevada. A used car salesman and father, he was murdered during what he thought was a routine test drive with a potential customer.
Investigation and Capture
Petrocelli’s spree across state lines left a trail for law enforcement to follow. The murder of Melanie Barker in Seattle immediately made him a wanted fugitive. After killing James Wilson in Reno, Petrocelli was eventually tracked down and arrested in Las Vegas in April 1982. At the time of his arrest, he was in possession of the .22 caliber semi-automatic pistol used to kill Wilson and Barker. He was also found with identification belonging to Dennis Gibson, which would prove crucial in linking him to the California murder more than two decades later. The investigation into a suspected fourth victim, British tourist Stephen Scane, was bolstered when Scane's ID was also found on Petrocelli at his arrest. Scane, a 26-year-old carpenter, had disappeared in Wyoming in late 1981. His skull was found in Utah in 1984. Although Petrocelli remains the primary suspect, he has never been charged in Scane's death.
Trial and Sentencing
Tracy Petrocelli faced separate legal proceedings in Nevada, Washington, and California for the three murders.
His first trial was in Reno in July 1982 for the murder of James Wilson. The prosecution presented evidence of Petrocelli's flight from Washington after killing Melanie Barker, arguing it established a pattern of behavior. Petrocelli claimed the shooting was an accident that occurred during a struggle. On August 6, 1982, a jury found him guilty of first-degree murder and armed robbery. He was sentenced to death.
In early 1983, Petrocelli was extradited to Washington to stand trial for the murder of Melanie Barker. He was convicted of first-degree murder and sentenced to life in prison without the possibility of parole.
For more than 25 years, the murder of Dennis Gibson remained unsolved. In 2008, armed with new ballistics evidence and the fact that Petrocelli possessed Gibson's ID upon his arrest, authorities in San Bernardino County, California, charged him with the murder. In 2009, Petrocelli was extradited from Nevada and pleaded guilty to second-degree murder. He was sentenced to 15 years to life in prison.
Appeals and Overturned Sentences
Petrocelli's 1982 death sentence in Nevada began a long and complex appeals process. His case became influential in Nevada law regarding the admissibility of "prior bad acts" as evidence. In 2017, the 9th U.S. Circuit Court of Appeals overturned his death sentence, ruling that his constitutional rights were violated. The court found that a psychiatrist hired by the prosecution had interviewed Petrocelli in jail without his lawyer present and without informing him of his Miranda rights, and then testified during the penalty phase that Petrocelli was a dangerous, incurable psychopath.
A new sentencing hearing was held in 2019, and a new jury once again sentenced Petrocelli to death. However, in May 2021, the Nevada Supreme Court overturned the death sentence for a second time. The court ruled that a wording error on the jury's verdict form misstated the legal standard for imposing a life sentence versus a death sentence, potentially confusing the jurors. The error, the court concluded, affected Petrocelli's substantial rights. As a result, he is entitled to another sentencing hearing in Nevada.
Aftermath and Legacy
Tracy Petrocelli remains incarcerated at Northern Nevada Correctional Center, awaiting a third penalty phase trial for the murder of James Wilson. He is serving concurrent life sentences for the murders in Washington and California. His legal challenges in Nevada have had a lasting impact on the state's criminal justice system, particularly in establishing stricter parameters for how a defendant's prior criminal history can be presented to a jury. For the families of Melanie Barker, Dennis Gibson, and James Wilson, the decades of legal proceedings have meant a prolonged and painful journey through the justice system. For the family of Stephen Scane, there has been no legal closure, as Petrocelli has never been charged with his murder, though he remains the only suspect.
