''DENVER (KDVR) — Authorities say that new technology has provided “decisive evidence that conclusively links” a suspect in the 1975 murder of 20-year-old John Curtis Patterson.
However, the suspect, identified as Louis Jess Locicero, then 32, had previously been suspected in the case and died in 2024''
''The case was reported on Sept. 29, 1975, in the 4500 block of North Broadway, where the Boulder County Sheriff’s Office found the body of 20-year-old John Curtis Patterson, a Cascade Service Station clerk, in the gas station’s restroom. The agency said Patterson had a fatal stab wound to his chest.
The agency recovered two unfired .30 caliber cartridges on the bathroom floor, near Patterson’s body. The agency said the cartridges had extractor marks and “light hit” indications on the primers.''

“The Boulder County Sheriff’s Office was evaluating the Ballistics IQ device from Evidence IQ which linked the cartridges found at the murder scene and cartridges found in Locicero’s nearby hotel room to a single firearm — Locicero’s .30 caliber M1 carbine,” the office reported Wednesday.''
