Keeley Koff, 32, was found dead inside a stolen pickup truck on the morning of August 29, 2025, in the 200 block of North 6th Avenue in Brighton, Colorado. She was about 14 weeks pregnant. An initial investigation reported she had sustained what appeared to be fatal gunshot wounds.

Investigators identified 50-year-old James Jaime Benavidez as the primary suspect. Benavidez was already in custody after an unrelated crime spree that began the previous day and included an attempted carjacking at a gas station, theft of another vehicle, a high-speed pursuit during which he fired at pursuing officers, and other violent charges. Surveillance footage showed Benavidez abandoning the pickup truck in the early morning hours of August 28, and Koff’s mother said Keeley had been staying with him in that truck.

Benavidez was charged with first-degree murder and unlawful termination of pregnancy, as well as multiple offenses from the separate crime spree, including attempted homicide of officers. If anyone knew Keeley, saw the truck on North 6th Avenue that week, or has other information, please share what is known.
