Investigators from the Lane County District Attorney’s Office quickly dismantled the phantom shooter defense. Downs insisted an unidentified man ambushed her family after asking for her car. Ballistics experts, however, discovered that all three children had been shot with a .22 caliber weapon, the exact caliber of a Ruger pistol Diane had previously owned in Arizona. While Downs claimed the weapon was stolen, investigators found unfired .22 caliber shell casings inside her Springfield home.

Forensic toolmark examiners linked the firing-pin strike impressions and extractor marks from the cartridge casings recovered at the crime scene directly to the test-fired casing extracted from Downs' residence. Blood spatter analysts also uncovered gunpowder residue inside Diane's vehicle, proving the weapon was fired from the driver’s seat inside the cabin, not from an outside attacker leaning through an open window.

Detectives then unlocked her motive through her private diaries. The journals revealed an unhinged, obsessive fixation on a married former coworker from Arizona named Robert Knickerbocker. Knickerbocker repeatedly told Downs he had no interest in raising three children. For Downs, the solution was chillingly utilitarian: eliminate the children to remove the barrier between herself and her lover.
