John Leonard Orr: Arson Spree, Convictions, and Sentencing

John Leonard Orr is a former Glendale, California, fire captain and arson investigator who was convicted of setting dozens of fires across Southern California in the 1980s and early 1990s, including a 1984 hardware store blaze that killed four people. A federal jury convicted him of arson in 1992, and a state jury found him guilty of four counts of first-degree murder in 1998. He is serving life in prison without the possibility of parole. Investigators believe he may have set as many as 2,000 fires during his years on the job.

A Firefighter Who Set Fires

Orr joined the Glendale Fire Department in 1974 and worked his way up to captain and chief arson investigator. Colleagues called him “The Professor” for his skill at pinpointing where and how a fire had started.¹ He claimed to have caught more than forty serial arsonists during his career, and author Joseph Wambaugh later described him as “probably the most prolific American arsonist” of the twentieth century.²

The fires Orr set followed a distinct signature. He built a time-delay incendiary device from a cigarette, matches, a rubber band, and a piece of yellow notebook paper. The cigarette burned as a slow fuse, giving him ten to fifteen minutes to walk away before the device ignited. He placed the devices in occupied retail stores during business hours, tucked into polyurethane foam displays, drapery and fabric sections, and hardware store shelving.³

His badge was his camouflage. Prosecutors later estimated he started well over 2,000 fires between 1984 and his arrest in 1991. He often volunteered to investigate the very fires he had set, sometimes overriding other investigators’ conclusions. His access to evidence eventually prompted colleagues to warn one another, “Tell John Orr to stop handling evidence.”⁴

The Ole’s Home Center Fire

The deadliest fire attributed to Orr broke out on October 10, 1984, at the Ole’s Home Center on Fair Oaks Avenue in South Pasadena. Four people died: employees Carolyn Kraus, 26, and Jimmy Cetina, 17; customer Ada Deal, in her early fifties; and Deal’s grandson, Matthew William Troidl, who was two or three years old.⁵⁶

The original investigation blamed an electrical malfunction in the attic. Prosecutors would later call that probe “slipshod.”⁶ Orr himself came to the scene and insisted, correctly, that the fire was arson. More than a decade passed before anyone realized the investigator naming it arson was the person who had lit it.⁴

The College Hills Brush Fire

On June 27, 1990, a brush fire ignited near Verdugo Road and Glendale Avenue in the College Hills neighborhood of Glendale. It was the worst fire in the city’s history, destroying forty-six homes, damaging twenty more, and jumping the freeway to burn additional structures. Damage estimates ran from $40 million to $50 million. No one died.⁷⁸ Orr was later convicted of setting that blaze.

How He Was Caught

The break came from Marvin Casey, a fire captain and arson investigator in Bakersfield. In 1987, Casey noticed that suspicious fires kept breaking out around arson investigator conferences. He cross-referenced attendee lists and identified a small group of investigators who had been at all of them. Orr’s name was on every list.⁹

The physical evidence had been waiting in a file since 1987. After a fire at a CraftMart store in Bakersfield, investigators had recovered one of the signature devices, and lifted a fingerprint from the yellow notebook paper. An initial 1989 comparison failed to match it to Orr. In the spring of 1991, a task force of local police and federal ATF agents ran the print again with improved technology, and it came back as his.⁴ Some task force members had assumed the print was contamination from Orr’s investigative work, but Casey insisted Orr had never had access to that particular piece of evidence.⁹ Federal agents arrested Orr on December 4, 1991.¹⁰

The Points of Origin Manuscript

After the arrest, investigators found a 104,000-word unpublished novel in Orr’s possession titled Points of Origin. The book followed a fictional firefighter named Aaron Stiles who moonlights as a serial arsonist. Prosecutors argued the plot contained details only the real arsonist could have known.¹¹

The parallels were extensive. Both the fictional arsonist and the real one were firefighters and non-smokers. Both used identical devices: matches attached to a cigarette, wrapped in paper. Both targeted retail drapery sections, polyurethane foam displays, and hardware stores during business hours. The fictional fires occurred at the same times and places as arson investigator conferences in Fresno. One passage described a hardware store fire that killed a woman and her toddler grandson, closely tracking the Ole’s Home Center deaths.¹²¹¹

The federal district court initially excluded the manuscript, ruling its prejudicial effect outweighed its probative value. The Ninth Circuit reversed in October 1992, holding that the book was “highly probative of modus operandi and thus the identity of the arsonist.”¹² Orr’s defense argued his knowledge of arson techniques came from his professional access to investigation files, and he later claimed investigators had used the book to frame him, insisting that Aaron Stiles was based on real arsonists he had caught.¹¹

The Federal Convictions

Orr faced two sets of federal indictments. The first, filed in Los Angeles in December 1991, charged him with eight counts of arson and attempted arson tied to fires in the Los Angeles area and near Atascadero. A second indictment in Fresno in January 1992 added five counts related to store fires in the San Joaquin Valley.¹³

The prosecution’s case rested on the CraftMart fingerprint; a black bag found in Orr’s car when he was arrested, containing matches, rubber bands, cigarettes, and lighters; the Points of Origin manuscript; and letters Orr had written to literary agents that showed detailed knowledge of the fires.¹⁴ The jury convicted him on three counts of arson, and he was sentenced to thirty years in federal prison. In 1993, he pleaded guilty to three more federal arson counts, including fires at a Builders Emporium in North Hollywood and a hardware store near Atascadero.⁵ The Ninth Circuit affirmed the convictions in July 1994, calling the evidence “very strong.”

The State Murder Trial

While Orr was serving his federal sentence, Los Angeles County prosecutors filed state charges: four counts of first-degree murder for the Ole’s Home Center fire and twenty-one counts of arson for fires set between 1990 and 1991 in Burbank, Glendale, and La Cañada Flintridge. The arson charges included the College Hills fire and a November 1991 fire on the Warner Bros. Studios back lot.⁵

The trial began in April 1998 in Los Angeles Superior Court before Judge Robert J. Perry. Deputy District Attorney Michael Cabral led the prosecution with Sandra Flannery. Peter Giannini represented Orr. More than a hundred witnesses testified, and prosecutors introduced forty videotapes and seventy audiotapes recorded at fire scenes. The manuscript again played a central role.⁵

In June 1998, the jury found Orr guilty of four counts of first-degree murder with special circumstances and twenty counts of arson. During the penalty phase, the jury deadlocked eight to four in favor of the death penalty. California law requires a unanimous verdict for a death sentence, and the District Attorney declined to retry the penalty phase. In September 1998, Judge Perry sentenced Orr to four consecutive life terms without parole, plus twenty years for the arson counts, and ordered him to pay $90,000 in restitution.¹⁵

Where Orr Is Now

Orr was transferred from federal to California state custody around 2002. As of early 2025, he was held at Mule Creek State Prison in Ione, California, where he writes for the prison newspaper, the Mule Creek Post.⁹¹⁶ He has published essays through the Prison Journalism Project.¹⁷ He continues to maintain his innocence, saying investigators used his manuscript to frame him.¹¹

Books, Film, and Television

Joseph Wambaugh’s 2002 nonfiction book Fire Lover: A True Story described Orr as an “eccentric loner” and “cop wanna-be” whose behavior at fire scenes had often struck colleagues as peculiar.² That same year, HBO released the film Point of Origin, directed by Newton Thomas Sigel, with Ray Liotta as Orr and John Leguizamo as his protégé.¹

In June 2025, Apple TV+ premiered Smoke, a nine-episode drama created by Dennis Lehane and starring Taron Egerton and Jurnee Smollett. The series is based on the 2021 podcast Firebug, hosted by Kary Antholis, which chronicled Orr’s crimes. Smoke relocates the story to a fictional Pacific Northwest town and updates it to the present, but its premise of an arson investigator who secretly sets fires comes straight from Orr’s case.¹⁸
