Brandon Arguello Lopez, a 30-year-old Hispanic man from Casper, Wyoming, was shot during the evening of February 1, 2024, in the 1500 block of West 15th Street and died at 3:40 a.m. on February 2 at a local hospital. Officers found him on the ground with a gunshot wound to the head; the Natrona County Coroner’s autopsy determined the bullet entered the back, traveled through the spinal column and lodged in the brain, and ruled the death a homicide. Emergency responders found Lopez lying atop a box of individually wrapped marijuana packages, and toxicology showed amphetamines in his system.

Investigators initially described the scene as complex but said it appeared isolated and not a threat to the public. Court testimony later described the shooting as occurring during a drug deal that went wrong; witness testimony included claims Lopez said he had a gun and that three gunshots were heard.

Did anyone in the Casper area see activity near West 15th and Cottonwood that night or know Lopez’s movements before the shooting?
