The Sample Beneath the Door

One laboratory sample from the Willingham house tested positive for an accelerant. It came from beneath an aluminum threshold at the front door. § CASE FILE ▪ Case: Cameron Todd Willingham ▪ Jurisdiction: Navarro County, Texas ▪ Period: 1991 — 2011 ▪ Disposition: Conviction upheld on appeal; executed in 2004 ──────────────────────────── THE THRESHOLD On December 23, 1991, a fire destroyed a home in Corsicana, Texas. Cameron Todd Willingham escaped. His three young daughters did not. Investigators concluded that the fire had been deliberately set. Burn patterns across the floors, cracked window glass, low burning, melted aluminum and a laboratory result from beneath the front doorway were presented as evidence of an accelerant. The jury convicted Willingham of capital murder. Years later, fire scientists began examining the same evidence under standards that had changed substantially since the original investigation. ▪ Floor patterns described at trial as evidence of poured liquid ▪ A single debris sample that tested positive for mineral spirits ▪ A melted container of charcoal lighter fluid found outside the doorway ▪ Aluminum that investigators said could only have melted in an accelerant-fed fire ▪ Later scientific reviews challenging the indicators used to classify the fire as arson ▪ An execution carried out four days after a fire scientist submitted findings disputing the state's case In 2011, the Texas Forensic Science Commission published its final report. It found that several indicators relied upon in the original investigation could be produced without an accelerant and that ordinary fuels and liquid fuels burn at similar flame temperatures. The laboratory sample beneath the threshold remained positive. Its source could no longer be tested. No authority has ever determined what started the fire, and Willingham's conviction has never been vacated. § IN THE RECORD Texas Court of Criminal Appeals opinions · Texas Forensic Science Commission report · Trial testimony · Laboratory findings · Gerald Hurst review · Innocence Project fire panel · The New Yorker reporting · Chicago Tribune reporting · Contemporary interviews and public records Where the record ends, the episode says so. ──────────────────────────── ▪ This narration features AI-assisted voice production. ▪ No dialogue is invented.
