How 'MythBusters' Helped a Wrongly Convicted Man Prove His Innocence

"John Galvan was arrested at 18 and spent 35 years in prison for a crime he didn't commit," writes the Innocence Project, a nonprofit specializing in legal exoneration. "In 2007, John Galvan was about 21 years into a life sentence for a crime he didn't commit when he saw something on the prison television he thought might finally help him prove his innocence and secure his freedom: A re-run of an episode of the Discovery Channel's MythBusters." At the time of his arrest, they write, Galvan had been handcuffed to a wall for hours, physically beaten, and ultimately "agreed to give a confession that was completely fabricated by the detectives to end the abuse" — that Galvan had started a fire in an apartment building "by throwing a bottle filled with gasoline at the building and then tossing a cigarette into the pool of gasoline on the porch to ignite it." And then 21 years later... In his cell, a 39-year-old John watched as the hosts of MythBusters struggled repeatedly to ignite a pool of gasoline with a lit cigarette, despite fervent attempts. Based on the ignition temperature of gasoline and the temperature range of a lit cigarette, the show's hosts had initially hypothesized that a lit cigarette might be able to ignite spilled gasoline as they had seen on TV and in movies. But after several failed attempts to start a fire, including rolling a lit cigarette directly into a pool of gasoline, the team determined it was highly unlikely that dropping a cigarette into gasoline could cause a fire.... The show's findings were confirmed in 2007, by experiments conducted by the U.S. Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), which made more than 2,000 attempts to ignite gasoline with a cigarette under various conditions. The bureau's experiments even included a vacuum that increased the cigarette's temperature to the level it would typically reach when being sucked and spraying a mist of gasoline directly onto the lit cigarette. All of the attempts failed. "Despite what you see in action movies, dropping a lit cigarette on to a trail of gasoline won't ignite it, assuming normal oxygen levels and no unusual circumstances," said Richard Tontarski, a forensic scientist and then chief of the ATF's fire research laboratory. In 2017, when John finally had his evidentiary hearing on his post-conviction claims, [his attorney Tara] Thompson and his legal team presented multiple alibi witnesses, in addition to seven witnesses who testified to being tortured by the same officers who had coerced his confession, documents showing that police had fabricated probable cause to arrest him, and an arson expert who testified that John's false confession was scientifically impossible.... In 2019, the appellate court granted John post-conviction relief on the grounds of actual innocence — a rarity in Illinois — largely based on the abuse used to coerce a false confession from John. The court concluded that without John's false confession, which he did not give voluntarily, "the State's case was nonexistent."
