On the evening of Wednesday, November 1, 2017, 52-year-old Pamela Marques of Denver was inside a Walmart Supercenter in Thornton, Colorado, when a gunman opened fire around 6:10 p.m. Marques was critically wounded in the shooting, taken to a local hospital, and later died of her injuries. Two other shoppers, Carlos Moreno, 66, and Victor Vasquez, 26, were also killed.

Witnesses reported the shooter walked into the store and began firing randomly before fleeing; police apprehended 47-year-old Scott Allen Ostrem the next day after a brief chase in Westminster. Neighbors described Ostrem as a loner who was often angry and rude, and he had prior arrests. Motive remained unclear and investigators had not officially determined whether the killings were a hate crime.

Ostrem was charged with multiple counts of first-degree murder and attempted murder and, after a competency evaluation, a judge found sufficient evidence to proceed. Does anyone have information about Marques or memories of that night that could help build a fuller picture of her life and the victims?
