The Marks of a Missing Gun

from Material Fact: True Crime · host Material Fact

Rounds of .22 caliber ammunition were taken from a house in Springfield, Oregon. None had ever been fired. According to the ballistics experts who examined them, they still carried the marks of a gun. § CASE FILE ▪ Case: State v. Diane Downs ▪ Jurisdiction: Lane County, Oregon ▪ Period: 1983 — present ▪ Disposition: Conviction upheld ──────────────────────────── THE UNFIRED ROUNDS In May 1983, Diane Downs arrived at a hospital with her three children. All three had been shot. One died. Downs told investigators that a stranger had attacked them on a rural road and wounded her as she escaped. The weapon was never recovered. But investigators found something else: unfired ammunition inside Downs's home carrying extractor marks that ballistics experts testified matched marks found on spent casings from the crime scene. ▪ Three children shot on a rural Oregon road ▪ An unidentified stranger described as the attacker ▪ A missing .22 caliber semiautomatic pistol ▪ Unfired ammunition carrying marks attributed to the same type of weapon ▪ A surviving child whose testimony would later become central to the trial The gun disappeared. Its marks did not. § IN THE RECORD Federal appellate opinion · Trial reporting · Contemporary news coverage · Investigative interviews · Ballistics testimony Where the record ends, the episode says so. ──────────────────────────── ▪ This narration features AI-assisted voice production. ▪ No dialogue is invented.
